Practical and Efficient 1α-Hydroxylation of 4,4-Dimethyl-2-Ene Derivatives in Terpenic Series

Abstract The third part of a triptycal synthesis providing 1α-hydroxy compounds, through microbial hydroxylation in position-3 of terpenoid substrates, followed by dehydration to 4,4-dimethyl-2-ene compounds and subsequent allylic hydroxylation by SeO2/pyridine N-oxide, is described.
