Alternate and Improved Synthesis of the Cactus Alkaloid Arizonine
摘要:
An alternate and high-yield synthesis of the simple tetrahydroisoquinoline alkaloid arizonine, via the sodium cyanoborohydride mediated reductive amination of 2-benzyloxy-3-methoxyacetophenone with aminoacetaldehyde diethyl acetal, as the key step, is reported.

A newapproach to the synthesis of 7,8-dioxygenated tetrahydroisoquinoline alkaloids based on the phot-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.
