摘要

A simple variation of the Pomeranz-Fritsch cyclization provides a short, efficient route to isoquinolines. Treatment of benzylic halides or mesylates 1 with the sodium anion of N-tosyl aminoacetaldehyde dimethyl acetal (2) followed by acid-catalyzed cyclization provides an effective, two-step preparation of isoquinolines 4.
