摘要:
The synthesis of novel chiral propargylic epoxides ((R)-1-t-butyldimethylsilyl-3,4-epoxy-1-butyne, (3S,4S)-3,4-epoxy-1-octyne, (3R,4S)-1-t-butyldimethylsilyl-3,4-epoxy-l-pentyne) has been developed starting from the readily available tartaric acid derivative, (S,S)-(+)-2,3-O-isopropylidene-L-threitol.
