Organocatalytic asymmetric assembly reactions for the syntheses of carbohydrate derivatives by intermolecular Michael-Henry reactions.
Given the significance of carbohydrates in life, medicine, and industry, the development of simple and efficient de novo methods to synthesize carbohydrates are highly desirable. Organocatalytic asymmetric assembly reactions are powerful tools to rapidly construct molecules with stereochemical complexity from simple precursors. Here, we present a simple and robust methodology for the asymmetric...
متن کاملSyntheses of Anisomycin Derivatives
The structure of anisomycin has been determined by X-ray investigation4 and the absolute configuration was confirmed by chemical correlation.5 Anisomycin has attracted considerable synthetic interest, and several synthetic studies, derivative syntheses as well as total syntheses, have been reported.6 Especially, the synthesis of its analogues has revealed the structure-activity relationship of ...

متن کاملSyntheses of furo[3,4-c]coumarins and related furyl coumarin derivatives via intramolecular Wittig reactions.
A new and general strategy for highly functional furo[3,4-c]coumarins and related furyl coumarin derivatives has been developed, which is based on an extraordinarily facile intramolecular Wittig reaction, starting from α,β-unsaturated ketones, tributylphosphine, and acyl chlorides. The phosphorus ylides were proposed to be the key intermediates for constructing the crucial furan ring, leading t...
