Enzyme assisted preparation of enantiomerically pure β-adrenergic blockers II. Building blocks of high optical purity and their synthetic conversion
摘要:
Based on previous screening results a series of potential building blocks 2-4 for beta-adrenergic blockers were prepared both by enzymatic hydrolysis and acyltransfer and further transformed into the corresponding oxiranes and aminoalcohols of defined absolute configurations.
