Abstract
Abstract: Lewis acid (BF3) catalyzed allylation of quinones with allyl-(Za), 2-methyl-2- propenyl-(Zb), trans-2-butenyl-(2c, d), 3-methyl-2-butenyl-(2e, f), and trans- cinnamyltrialkyltin (2g) gives the corresponding allylhydroquinones with high regioselectivity. Vitamin K2 (5)(7) and coenzyme Q1 (9) were prepared in yields of 78 and 75%, respectively. These reactions appear to proceed through allylquinol intermediates ...
