STEREOSPECIFIC ACETOXYLATION OF 4-METHYL-4-DICHLOROMETHYL-5-(METHOXYCARBONYL)METHYL-2-CYCLOHEXEN-1-ONE WITH LEAD(IV) ACETATE

Acetoxylation of 4-methyl-4-dichloromethyl-5-(methoxycarbonyl)methyl-2-cyclohexen-1-one with lead(IV) acetate in the presence of Lewis acids gives the corresponding 6-trans-α-acetoxylated derivative which, in an excess of boron trifluoride etherate (or in acidic media), undergoes cyclization to a trans-γ-lactone.
