Abstract
Lipase Amano PS catalysed acylation of (+/-)-2-hydroxymethyl-2,3-dihydroben zofurans using vinyl acetate as the acyl donor in n-hexane gave (-)-(R)-2-a cetoxymethyl-2,3-dihydrobenzo and (+)-(S)-2-hydroxymethyl-2,3-dihydrobenzof urans in high enantiomeric excess. (-)-(R)-Acetate 18j is converted to (-)- (R)-MEM-protected arthrographol 22. (C) 2000 Published by Elsevier Science Ltd.
