RESUMO

The title compound, C(8)H(8)Br(2)O(2), was synthesized from the hydrolysis of 1,4-dibromo-2,3-bis-(bromo-meth-yl)benzene. One intra-molecular O-H⋯O and two intra-molecular C-H⋯Br inter-actions occur. In the crystal, mol-ecules are linked into a chain running parallel to [010]. Adjacent chains are linked into a two-dimensional layer by a combination of inter-molecular O-H⋯O hydrogen bonds and C-H⋯π inter-actions.

RESUMO

The title compound, C(16)H(12)O(2), was synthesized from naphthalene-2,7-diol and prop-2-ynyl 4-methyl-benzene-sulfonate in the presence of sodium hydride. The crystal packing exhibits inter-molecular non-classical C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

RESUMO

Employing simple and readily available aromatic ketones and anilines as starting materials resulted in the construction of 2-acylbenzothiazoles via a novel self-sequence reaction network, which assembles six reactions in one pot. The reaction network not only supplied a novel method for constructing complex molecules but also provided a typical example for logical self-organization synthesis.

RESUMO

A highly efficient method for the synthesis of oxazole derivatives from methyl ketones, benzoins and ammonium acetate has been established via a novel strategy-convergent integration of two self-labor domino sequences. Owing to the simple and readily available starting materials, mild reaction conditions, facile operation, and the high bioactivity of oxazole derivatives, this reaction promises diverse applications in medical chemistry. Additionally, this reaction could provide an efficient example for self-labor synthesis strategy of organic compounds.

RESUMO

Functionalized chromenes have been synthesized via highly selective metal-free domino reactions from ketones and phenols. 2H-Chromenes, 4H-chromenes, spiran and benzocyclopentane can be respectively prepared starting from the corresponding cyclic ketones, aryl methyl ketones, acetone, and 3-pentanone.

RESUMO

An unexpected rearrangement aromatization of benzo[c]oxepine has been revealed to synthesize substituted naphthalenes. This observation was further exploited to develop an efficient approach for the construction of naphthalenes from simple and commercially available 1,3-dicarbonyl compounds and 1,2-bis(halomethyl)benzene compounds via a new domino reaction sequence.
