Total syntheses of naturally occurring diacetylenic spiroacetal enol ethers

A highly stereoselective method for constructing a (2E)-methoxymethylidene- 1,6-dioxaspiro[4.5]-decane skeleton has been developed on the basis of the palladium(II)-catalyzed ring-closing reaction of the 3,4-dioxygenated-9-hydroxy- 1-nonyn-5-one derivativ

First total synthesis of (-)-AL-2

(Matrix presented) Treatment of the 3,4-dioxygenated-9-hydroxy-1-nonyn-5-one derivative, derived from diethyl L-tartrate, with a palladium catalyst in methanol under a CO atmosphere effected an intramolecular acetalization and a stereoselective constructi
