Abstract Subtilisin DY as well as alkaline protease from Bacillus licheniformis 41 p catalyze the hydrolysis of (1SR, 5RS, 6RS, 7RS)-7-acetoxy-6-acetoxymethyl-2-oxabicyclo [3.3. 0] octan-3-one (rac-1) with practically useful enantio-and regioselectivity. Under the hitherto found optimal conditions (1S, 5R, 6R, 7R)-7-hydroxy-6-hydroxymethyl-2-oxabicyclo [3.3. 0] octan-3-one (4), an important intermediate in prostaglandin syntheses, could be prepared ...
