SYNTHESIS OF ALL FOUR POSSIBLE STEREOISOMERS OF 1-PHENYL-2,3-BUTANEDIOL AND BOTH ENANTIOMERS OF 3-HYDROXY-4-PHENYL-2-BUTANONE TO DETERMINE THE ABSOLUTE CONFIGURATION OF THE NATURAL CONSTITUENTS
摘要:
Enantioselective syntheses of all the possible stereoisomers of 1-phenyl-2,3-butanediol (erythro isomer 1 and threo isomer 2) and of 3-hydroxy-4-phenyl-2-butanone 3, the odor components of wisteria flowers, was accomplished via Sharpless asymmetric epoxydation. The absolute configurations of 13 were determined by an HPLC analysis of the corresponding MTPA esters of synthetic samples.
