A stereochemically controlled synthesis of the cis-(Z)-4-isomer (26; R = Me) of methylbixin is described, which involves 5-methoxycarbonyl-3-methylpenta-cis-(Z)-2,trans-(E)-4-dien-1-al (6) as the key intermediate. The product is shown to be identical with the methyl ester of natural bixin.
描述了立体化学控制的甲基联蛋白的顺-(Z)-4-异构体(26; R = Me)的合成,涉及5-甲氧基羰基-3-甲基五-顺-(Z)-2,反-(E) -4-dien-1-al(6)作为关键中间体。显示该产物与天然联鑫的甲酯相同。
