Total synthesis of acetylenic carotenoids. 3. First total synthesis of optically active 9-Z-(3R,3'R)-diatoxanthin and 9-Z-(3R)-7,8-didehydrocryptoxanthin.

Optically active 9-Z-(3R,3'R)-diatoxanthin and 9-Z-(3R)-7,8-didehydrocryptoxanthin were synthesised in an overall yield of 9percent and 11percent respectively, with a seven step C9+C6+C25=C40 strategy.A key intermediate was the previously undescribed C15-
