Carotenoids and related polyenes. Part 9.1 Total synthesis of thermozeaxanthin and thermocryptoxanthin and the stabilizing effect of thermozeaxanthin on liposomes

Abstract

Thermozeaxanthin and thermocryptoxanthin are efficiently synthesized via β-selective glucosidation of (3R)-3-hydroxy-β-ionone 7, and the stabilizing effects of zeaxanthin 5, its glucoside 3 and thermozeaxanthin-15 1a on liposomes are also examined.
