Synthesis of melodienone and 7-hydroxy-6-hydromelodienone, two heptenes from Melodorum fruticosum.
摘要:
An unified approach to the construction of the seven carbon atom framework of the title compounds having a gamma-oxoacrylate moiety as common structural feature, utilizing an intermolecular [3+2] cycloaddition of the nitrile oxide generated from a malic acid derived C-4 aldehyde fragment with methyl acrylate, is described.
