Synthesis of diastereomerically pure acetals of 1-phenylpropiophenone

摘要

Reaction of 1-phenylpropiophenone 1 with 1,2-O-isopropyli-dene-alpha-D-glucofuranose 2 is reported for the preparation of diastereomerically pure acetals namely,l,2-O-isopropylidene-5,6-O-(R/S)-phenylpropylidene-alpha-D-glucofuranose (3a,3b).
