Acid-catalyzed solvolysis of polyenol ethers. II. Effect of the degree of unsaturation

The acid-catalyzed solvolysis of polyenol ethers of glycerol gradually changes with increasing unsaturation from the regular pattern into an anomalous one in which hydroxy- and methoxy-substituted aldehydes are formed.

A CONVENIENT SYNTHESIS OF FECAPENTAENE-12 BY THE HORNER-WITTIG REACTION

A synthesis of racemic fecapentaene-12 and other glyceryl enol ethers has been developed based on the Horner-Wittig reaction.Coupling of the anion of the glyceryl substituted phosphine oxide 7 with unsaturated aldehydes 9a-c provided, after treatment with base, the silyl protected glyceryl enol ethers 11a-c.The silyl groups were easily removed and mixtures of E and Z isomers of glyceryl enol ethers 12a-c were obtained.The isomers could be separated upon washing with ether/hexane.
