Chirality Transfer from the Oxidative Dearomatization of Axially Chiral Binols with Oxone under Mild Conditions.

Easily accessible axially chiral substituted binols (95 to >99% ee) undergo an oxidative dearomatization process with the system Oxone/NaHCO3/acetone, under mild conditions, to afford pentacyclic hemiacetalic cis-diols (94 to >99% ee), bearing two new stereogenic centers, through an efficient axial-to-central chirality transfer.

Generation of two induced pluripotent stem cells lines from Mucopolysaccharydosis IIIA patient: IMEDEAi004-A and IMEDEAi004-B.

Mucoplysaccharydosis IIIA (MPSIIIA) is the most severe form of Sanfilippo syndrome. Skin fibroblasts from a MPSIIIA compound heterozygous (E447K/R245H) patient were nucleofected with four OriP/EBNA1-based episomal plasmids containing: OCT3/4, SOX2, KLF4, L-Myc, LIN28, BCL-xL and shp53. The two iPSCs lines generated carry both sulfamidase enzyme (SGSH) mutations, are free of plasmid integration, have normal karyotype, express pluripotency-associated markers and are able to differentiate into the three germ layers.
