Abstract
Starting with (+)-verbenone, readily obtainable from (+)-nopinone, enantioselective preparation of (S)-(+)-4-isopropenyl-,(S)-(−)-4-isopropyl-and (R)-(+)-4-(1-acetoxy-1- methylethyl)-3-methyl-2-cyclohexen-1-ones was accomplished with little loss of stereochemical integrity via BF3-induced cyclobutane-opening of (+)-4-(methylene) nopinone. As we have developed an efficient chemical transformation of (+)-nopinone into ...
