Abstract

Procaryotic (bacterial) dioxygenase-catalysed asymmetric dihydroxylation of chromene and 2, 2-dimethylchromene to yield the (4S)-enantiomers of the corresponding cis-diols exclusively is reported. The epoxide, and derived cis-and trans-diol products from the previously reported eucaryotic (mammalian) metabolism of precocene-1 (7-methoxy-2, 2- dimethylchromene), and the corresponding epoxide and diol derivatives of chromene and ...
