    • The yields of the unreacted diol (2) and the diacetate (3) produced from monoacetate (4) measuredby GC analysis were about 0.7% and about 0.2%, respectively. We did not isolate them.

    • Although 3 was also subjected to hydrolysis with other lipases, satisfactory results for the ee values of (S)-4 could not be obtained. Hydrolysis of 3 with Lipase ALC (Meito) yielded (S)-4 in 82% ee, while with Lipase PPL (Amano) did (R)-4 in 64% ee.
