Total synthesis of cucurbitaxanthin A, cycloviolaxanthin and capsanthin 3,6-epoxide by applying a regioselective ring opening of tetrasubstituted epoxides

The synthesis of 3,6-epoxy carotenoids cucurbitaxanthin A 1, cycloviolaxanthin 2 and capsanthin 3,6-epoxide 3, was accomplished via the C15-3,6-epoxides 20e and 20f, prepared by the regioselective ring opening of the 3-hydroxy-5,6-epoxides 10e

Total synthesis of capsanthin and capsorubin using Lewis acid-promoted regio- and stereoselective rearrangement of tetrasubsutituted epoxides

The synthesis of capsanthin 1 and capsorubin 2 was accomplished via the C15-cyclopentyl ketone 6 prepared by Lewis acid-promoted regio- and stereoselective rearrangement of the epoxy dienal 5. The Royal Society of Chemistry.

First total synthesis of cucurbitaxanthin A applying regioselective ring opening of tetrasubstituted epoxides

The synthesis of cucurbitaxanthin A 1 was accomplished via the C 15-3,6-epoxides 7e and 7f prepared by regioselective ring opening of the 3-hydroxy-5,6-epoxides 6e and 6f.

Total synthesis of capsanthin using Lewis acid-promoted regio- and stereoselective rearrangement of tetrasubstituted epoxide

The synthesis of capsanthin 1 was accomplished via the C15-cyclopentyl ketone 13 prepared by Lewis acid-promoted regio-and stereoselective rearrangement of the epoxide 12.
