Synthesis of 8-oxoberbines and related benzolactams by Pd(OAc) 2-catalyzed direct aromatic carbonylation

A variety of alkoxy-substituted benzolactams with a berbine or yohimbane skeleton were prepared from 1-benzyl-1,2,3,4-tetrahydroisoquinolines or 1-benzyl-1,2,3,4-tetrahydro-β-carbolines by a phosphine-free Pd(II)-catalyzed direct aromatic carbonylation in a Pd(OAc)2-Cu(OAc) 2 catalytic system. The site selectivity was compared with that of the carbonylation with Pd(OAc)2 or Pd(OAc)2·2 PPh3, respectively.
