✦ Synopsis

Technical Procedures for the Synthesis of Carotenoids and Related Compounds from 6‐Oxo‐isophorone, VI. Synthesis of Rhodoxanthin and (3__RS__, 3′RS)‐Zeaxanthin; Routes to the C~15~‐Ring Component via 3‐Oxo‐ionone Derivatives

The C~15~‐ring component 4, key intermediate of a new scheme for the synthesis of rhodoxanthin (1) and (3__RS__, 3__RS__)‐zeaxanthin (3), has been synthesized starting from 6‐oxo‐isophorone (7) via 3‐oxo‐cyclocitral and 3‐oxo‐ionone derivatives.
