A Facile Route to a Sensitive Terpene Alcohol : Regio-unselective Metalation of alpha-Terpinene as Key Step

Treatment of a-terpinene (I, R = H) with BuLi-KOCMe3 followed by FB(OMe)2 and then alk. H2O2 soln. gave 44% anthemol (I, R = OH). The metalation step of a-terpinene presumably gave 3 pentadiene-K species (II-IV), which reacted with D2O and ClSiMe3 to give I, V, or VI (R = D, SiMe3) resp. [on SciFinder (R)]
