ChemInform Abstract
While the reaction of the cinnamyl alcohol (I) with Weitz′ aminium salt (II) affords cinnamaldehyde (III), the coupling product (IV) and ( .+-.)-sesamin (V), the cinnamyl acetate (VI) produces analogous coupling products together with the dibenzoazepine derivative (VII). The cinnamates (XI) react in the same manner to produce the dibenzoazepines (XII) as sole products.
