摘要

A new and general synthesis of methyl isoquinoline-3-carboxylates is described starting from aromatic 1, 2-dialdehydes by reaction with protected phosphonoglycine derivatives. Methyl 1-oxo-1, 2-dihydroisoquinoline-3-carboxylates are obtained from 2-formylbenzoate derivatives. This new method allows the preparation of isoquinolines having electron- withdrawing groups on the benzene ring.
