Reissert compound chemistry. Part II. Synthesis of 1-benzylisoquinolines via the Reissert carbanion generated with sodium hydride
Abstract
An improved procedure for the preparation of 1-benzylisoquinolines in high overall yields via Reissert compound intermediates has been developed. It involves generation of the C-1 carbanion of the Reissert compound with sodium hydride in dimethylformamide.
