β¦ Synopsis
We have developed a number of efficient protocols for the facile synthesis of 1,2,3,4-tetrahydroisoquinolin-1-ones. This synthetic methodology allowed concise and efficient exploration of the SAR in all areas of the molecule. A number of these methods proved to be versatile, efficient and amenable to parallel synthesis.

When N-chloroacetyl-3-hydroxybenzylamine (37) in aqueous acetonitrile was irradiated, both ortho and para photocyclizations with reference to the OH group occurred to give 7-and 5 -hydroxy -3 -oxo -1,2,3,4tetrahydroisoquinolines ($2, 53). Similarly, 1 -methylisoquinoline derivatives (54, 55) were sy
