The Polonovski-Potier reaction of trans and cis berbines N-oxides was studied. The 8-cyano derivative obtained from trans N-oxides were used to synthesize 8-hydroxymethyl and 8-methyl berbines. This procedure was applied to the stereocontroled synthesis of (8R, 14S)-(-)-8-methylcanadine from (14S)-(-)-canadine. (C) 2000 Elsevier Science Ltd.
