With zinc dust in aq. NH4Cl/THF, mytenyl bromide (1) reacts with aldehydes (2) to give simple new pinene alcohols (beta-pinene-3-yl carbinols) (3), which are enantiomerically pure (100% de). The configuration of the new chiral centre at C-11 was determined by oxidation to the ketone 4 and stereoselective reduction to Cram alcohol 3.
