Cholesterol absorption inhibitor drug SCH 47949 is synthesized stereoselectively using an artificial intelligence design proposed by SYNSUP. The key step involves a stereoselective one-pot preparation of the trans-β-lactam system through thermal electrocyclization. The trans-β-lactam intermediate is converted to SCH 47949 by a series of functional group transformations proposed by SYNSUP.
