Synthesis of homophthalates from allenic diesters: Conversion into viocristin and analogues, and application to 6-methylpretetramid

Oxy-substituted homophthalic anhydrides have been synthesized by cycloaddition of di- and tri-oxy butadienes to the allenic diester (1). By base-catalysed cycloaddition to appropriate benzoquinones they have afforded new syntheses of viocristin (19), isov

A New Approach towards Synthesis of Linear Natural Phenolic Products

A repetitive strategy for the synthesis of linear natural phenolic products involving reaction of two lithium enolate molecules of t-butyl acetate with esters of dicarboxylic acids is reported.
