A facile synthesis of 4,6-O-benzylidene-d-glycals via 1,5-anhydro-4,6-O-benzylidene-d-hex-1-en-3-ulose
摘要:
Benzylidenation of readily available 1,5-anhydro-D-hex-1-en-3-ulose, followed by sodium borohydride reduction, afforded the title compounds in high yields. Separation of 4,6-O-benzylidene-D-allal and -D-glucal was accomplished by selective acetylation with lipase PS. (C) 2008 Elsevier Ltd. All rights reserved.
