Versatile amine-promoted mild methanolysis of 3,5-dinitrobenzoates and its application to the synthesis of Colorado potato beetle pheromone

A mild deacylation method for 3,5-dinitrobenzoates using methanolic solutions of amines, such as dialkylamines, was developed. The method’s versatility was confirmed by applying it to synthesizing a key intermediate for Colorado potato beetle pheromone.

First Total Synthesis of (+/-)-Peridinin, (+/-)-Pyrrhoxanthin and the Optically Active Peridinin

The first total synthesis of peridinin 1 and pyrrhoxanthin 2 has been accomplished via the reaction of the C15-epoxy formyl ester 21 with the C22-allenic sulfone 28 or the C22-acetylenic sulfone 39.A synthesis of the optically active peridinin has also be

Synthesis of the 4-Alkylidenebutenolide Carotenoids, Peridinin and Pyrrhoxanthin

A novel synthetic method of carotenoidal alkylidenebutenolides has been developed, and applied to the first synthesis of peridinin (1) and pyrrhoxanthin (2).
