T. Yamano et al., A practical method for optical resolution of racemic alcohols or esters via lipase-catalyzed transformation and sulfation, CHEM LETT, (5), 2000, pp. 448-449
Optically active esters were conveniently obtained from the corresponding r
acemic alcohols or esters by lipase-catalyzed transformation, followed by s
ulfation. Sulfation by sulfurtrioxide pyridine complex enabled facile isola
tion of optically active esters by extraction instead of laborious column c
hromatography. The method would be especially advantageous on a large scale
