Reduction of Enamines of the 3,3-Dialkyl-3,4-dihydroisoquinoline Series

Article abstract of DOI:10.1007/BF00473462

Lithium aluminum hydride reduced enamines of the 3,3-dialkyl-3,4-dihydroisoquinoline series to the corresponding tetrahydroisoquinolines.In the presence of a hydrogen atom at the β-carbon atom of the enamino ester the action of lithium aluminum hydride and alkylmagnesium bromide leads to the products from the condensation of two molecules of the initial compound.
