Studies on Ergot Alkaloids and Related Compounds. XIV. Syntheses of N-Alkyl-4-methyl-2, 3, 4, 4a, 5, 6-hexahydrobenzo [f] quinoline-2-carboxamides and Stereochemistry of Diethyl 4-Methyl-1-oxo-1, 2, 3, 4, 4a, 5, 6, 10b-octahydrobenzo [f] quinoline-2, 2-dicarboxylate.

Abstract

Preparations of diethyl-, n-butyl-and 2-hydroxyisopropylamide derivatives of 4-methyl-2, 3, 4, 4a, 5, 6-hexahydrobenzo [f] quinoline-2-carboxylic acid (VI) were described. And the stereochemistries of diethyl 4-methyl-1-oxo-1, 2, 3, 4, 4a, 5, 6, 10b-octahydrobenzo [f] quinoline-2, 2-dicarboxylate (II) and related compounds were also discussed.
