Chemobiological transformations of octalone and hydrindenone derivatives
摘要:
Examples are given for allylic hydroxylations with Rhizopus arrhizus ATCC 11145. Chemical allylic hydroxylations are compared with microbiological ones. Stereoselective lipase-catalyzed hydrolyses are used efficiently.
The allylic hydroxylation of octalin derivatives with proceeds with high to excellent yields, even in the presence of substituents such as acetate, phosphate, free ketone or dioxolane, but not a benzyl group. One of the Me groups of a t-Bu ether can be hydroxylated.
