The structure and synthesis of a tetrahydro-β-carboline alkaloid from Phalaris arundinacea: some new tetrahydro-β-carbolines

Abstract

The original structure of 2,9-dimethyl-6-methoxy-1,2,3,4-tetrahydro-β-carboline for a new alkaloid from Phalaris arundinacea has been shown to be incorrect by synthesis. 6-Methoxy-2-methyl-1,2,3,4-tetrahydro-β-carboline has been synthesised and is suggested as an alternative.
