α'-SILYLATED TERTIARY BENZAMIDES AS DUAL ORTHO- AND α'-CARBANION SYNTHONS. CARBODESILYLATIVE ROUTES TO ISOQUINOLINE AND DIBENZOQUINOLIZIDINE DERIVATIVES

Article abstract of DOI:10.1016/S0040-4039(01)93484-7

α'-Silylated benzamides 4a display both ortho (6)- and α'-carbanion (5h, 15) reactivities which are translated into new synthetic routes for isoquinoline (8, 18, 19) and protoberberine (11, 12) derivatives.
