Production of chirally pure amino alcohol intermediates, derivatives thereof, and uses thereof
A method of selectively preparing a chiral 2S-amino alcohol useful in preparation of an amide sulfonated or acylated with alkyl, substituted aryl or substituted heteroaryl is described. The method involves reacting a di-tert-butyl diazene-1,2-dicarboxylat

A rapid access to both enantiomers of 1,2,3,4-tetranor B-trienic 18,18,18-trifluorosteroids. The first enantiocontrolled total synthesis of 18,18,18-trifluorosteroids
Chiral A-tetranor B-trienic 18,18,18-trifluorosteroid 2a and its enantiomer 1a were synthesised by the thermolysis of chiral olefinic benzocyclobutenes 7b and 7a which were in turn prepared by the aldol reaction of chiral oxazolidinone 5 and 11 with 2-(4-
