  摘要：

  AbstractSix keto carotenoids (4, 5, 6, 11, 12, and 22) were synthesized from intermediates which were prepared from the condensation products of mesityl oxide and acetoacetic ester. Compounds 4 and 22 can serve as precursors for zeaxanthin, while 5 can be used as an intermediate for xanthophyll. Echinenone and canthaxanthin were prepared by a new approach from vitamin A. Two new types of keto carotenoids with the keto functions incorporated into the unsaturated chain were prepared.
