A Case of Thoracic Endovascular Aortic Repair Using Carotid Access with Axillary-Carotid Bypass for Descending Aortic Aneurysm in a Patient with Aortoiliac Occlusive Disease.

The authors report a 71-year-old male with descending thoracic aortic aneurysm and multiple risk factors (aortoiliac occlusive disease, obesity, ascending aorta dilatation, and history of left ventriculoperitoneal shunt for hydrocephalus) who was treated with thoracic endovascular aortic repair (TEVAR) via left common carotid artery (LCCA) access and left axillary-carotid artery (Ax-CA) bypass; this approach shortened the LCCA clamp time during the procedure. The patient was discharged without any complications. TEVAR via LCCA access with left Ax-CA bypass is a useful and safe procedure for patients in whom conventional femoral artery access is not feasible.

Liquid enol ethers and acetates as gaseous alkyne equivalents in rh-catalyzed chemo- and regioselective formal cross-alkyne cyclotrimerization.

A cationic rhodium(I)/rac-BINAP complex catalyzes chemo- and regioselective formal cross-cyclotrimerizations of alkynes with enol ethers or acetates. Commercially available and cheap liquid enol ethers and acetates could be used as convenient gaseous alkyne equivalents in the present rhodium catalyses.

Rhodium-catalyzed regio- and stereoselective codimerization of alkenes and electron-deficient internal alkynes leading to 1,3-dienes.

A cationic rhodium(I)/H(8)-BINAP complex catalyzes codimerization of alkenes bearing no alpha-hydrogen and electron-deficient internal alkynes, leading to 1,3-dienes in good yields with moderate to excellent regio- and stereoselectivity. The same complex also catalyzes codimerization of an acrylate and phenyl-substituted electron-rich internal alkynes, leading to 1,3-dienes.

Rhodium-catalyzed highly enantio- and diastereoselective cotrimerization of alkenes and dialkyl acetylenedicarboxylates leading to furylcyclopropanes.

A cationic rhodium(I)/Segphos or H(8)-BINAP complex catalyzes the unprecedented cotrimerization of commercially available monoenes and dialkyl acetylenedicarboxylates, leading to functionalized furylcyclopropanes with excellent enantioselectivity and perfect diastereoselectivity.

Rhodium-catalyzed enantio- and diastereoselective intramolecular [2 + 2 + 2] cycloaddition of unsymmetrical dienynes.

A cationic rhodium(i)/(R)-H(8)-BINAP or (R)-Segphos complex catalyzes an intramolecular [2 + 2 + 2] cycloaddition of unsymmetrical dienynes, leading to fused tri- and tetracyclic cyclohexenes bearing two tertiary or quaternary carbon centers in high yields with high enantio- and diastereoselectivity.

Cationic rhodium(I)/segphos-catalyzed cycloisomerization of 1,6- and 1,7-diynes in the presence of 1,2-cyclohexanedione.

We have developed the first catalytic cycloisomerization of 1,6- and 1,7-diynes leading to trienes and vinylpyrroles by using a cationic rhodium(I)/Segphos complex (2.5-10 mol %) and 1,2-cyclohexanedione (100 mol %). 1,2-Cyclohexanedione may effectively occupy vacant coordination sites and thus promote the present cycloisomerization.

Synthesis of perfluoroalkylated benzenes and pyridines through cationic Rh(I)/modified BINAP-catalyzed chemo- and regioselective [2 + 2 + 2] cycloaddition.

A convenient synthesis of perfluoroalkylated benzenes and pyridines has been achieved by a cationic Rh(I)/modified BINAP-complex-catalyzed chemo- and regioselective [2 + 2 + 2] cycloaddition of alkynes with a perfluoroalkylacetylene and a perfluoroalkylnitrile.

[structure: see text]. We have developed a cationic rhodium(I)/Solphos complex-catalyzed asymmetric one-pot transesterification and [2 + 2 + 2] cycloaddition of 1,6-diyne esters with tertiary propargylic alcohols leading to enantioenriched tricyclic 3,3-disubstituted phthalides. The present method represents a versatile new route to the synthesis of enantioenriched tricyclic 3,3-disubstituted phthalides in view of the easy access to both coupling partners.

Rh-catalyzed [4 + 2] carbocyclization of vinylarylaldehydes with alkenes and alkynes leading to substituted tetralones and 1-naphthols.

Regio-, diastereo-, and enantioselective intermolecular [4 + 2] carbocyclizations of vinylarylaldehydes with alkenes and alkynes leading to substituted tetralones and 1-naphthols have been developed by using a cationic rhodium(I)/dppb or dppp complex as a catalyst.

Cationic Rh(I)/modified-BINAP-catalyzed reactions of carbonyl compounds with 1,6-diynes leading to dienones and ortho-functionalized aryl ketones.

We have determined that a cationic rhodium(I)/H8-BINAP complex catalyzes a [2 + 2 + 2] cycloaddition of both activated and unactivated carbonyl compounds with 1,6-diynes leading to dienones in high yields. On the other hand, unactivated aryl ketones react with 1,6-diynes in the presence of a cationic rhodium(I)/Segphos complex to give ortho-functionalized aryl ketones in high yields.

[structure: see text]. A cationic rhodium(I)/dppb complex catalyzed direct intermolecular hydroacylation of N,N-dialkylacrylamides with both aliphatic and aromatic aldehydes has been achieved through the stabilization of acylrhodium intermediates by alkene chelation to rhodium. This method represents a versatile new route to gamma-ketoamides in view of the high atom economy and commercial availability of substrates.

Rhodium-catalyzed reductive coupling of disulfides and diselenides with alkyl halides, using hydrogen as a reducing agent.

[reaction: see text] We have established that RhCl(PPh3)3 catalyzes a reductive coupling of disulfides and diselenides with alkyl halides in the presence of triethylamine using hydrogen as a reducing agent. This reaction serves as a convenient new method to produce unsymmetrical sulfides and selenides from disulfides and diselenides instead of unstable and odoriferous thiols and selenols.

Enantioselective synthesis of axially chiral biaryls through rhodium-catalyzed complete intermolecular cross-cyclotrimerization of internal alkynes.

[reaction: see text] We have developed a cationic rhodium(I)/H8-BINAP complex-catalyzed complete intermolecular cross-cyclotrimerization of internal alkynes with dialkyl acetylenedicarboxylates. This reaction was successfully applied to enantioselective synthesis of axially chiral biaryls utilizing internal alkynes bearing ortho-substituted phenyl and acetoxymethyl in each terminal position. The axial chirality is constructed at the formation of benzene rings with high enantioselectivity (up to 96% ee).

Surgical angioplasty for ostial atresia of left main coronary artery in child.

Ostial atresia of the left main coronary artery (LMCA) in children without any primary disease is extremely rare. We present here a case of occlusion of the LMCA in a 9-year-old girl. Myocardial scintigraphy showed poor perfusion in both domains of the left anterior descending artery (LAD) and left circumflex artery (LCx). Coronary artery graphy (CAG) showed complete ostial atresia of the LMCA and retrograde perfusion from the thin collateral arteries into the LAD. We performed angioplasty using an autologous pericardium onlay patch. Her postoperative course was unremarkable. Postoperative CAG showed vanishing collateral arteries, confirming anterograde flow through the LAD and LCx, and myocardial scintigraphy showed improvement in perfusion.
