New syntheses of 1-benzoyltetrahydroisoquinoline derivatives using polymer-supported bis(trifluoroacetoxyiodo)benzene

The reaction of N-benzenesulfonyl-β-phenethylamines with α-benzoyl sulfides using polymer-supported bis(trifluoroacetoxyiodo) benzene (PSBTI) gives moderate to good yields of the corresponding 1-benzoyltetrahydroisoquinoline derivatives.

Elaboration of 1-benzoyltetrahydroisoquinoline derivatives employing a Pictet-Spengler cyclization with α-chloro-α-phenylthioketones. Synthesis of O-methylvelucryptine

The reaction of N-tosyl-β-phenethylamines with α-chloro-α-phenylthioketones, leading to 1-benzoyl- and 1-pivaloyl-tetrahydroisoquinolines under modified Pictet-Spengler conditions, is described. The synthesis of O-methylvelucryptine employing this transformation as a key step is reported.
