Photochemical synthesis of 7,8-dioxygenated isoquinoline alkaloids

Suau, Rafael,Valpuesta, Maria,Torres, Gregorio

, p. 1315 - 1318 (2007/10/02)

A new approach to the synthesis of 7,8-dioxygenated tetrahydroisoquinoline alkaloids based on the photo-Fries rearrangement of esters derived from 3-hydroxy-4-methoxy phenylacetonitrile is reported. The procedure was applied to the synthesis of the alkaloid Arizonine and 1-benzyl tetrahydroisoquinoline precursor of cularine and 1,2-berbine alkaloids.
