of the two algal pheromones multifidene 1 and viridiene 2 were determined as (+)-(3S, 4S)-3-[(Z)-1-butenyl]-4-vinylcyclopentene and (+)-(3R, 4S)-3-[(1Z)-1, 3-butadienyl]-4-vinylcyclopentene, respectively. The strategy involves enzyme-initiated asymmetric synthesis of the ring-saturated pheromone analogues (+)-8a and (−)-8b and their subsequent catalytic hydrogenation to the chiral cycloalkanes 9a and
两个藻信息素multifidene 1和viridiene 2的绝对构型确定为(+)-(3 S,4 S)-3-[(Z)-1-丁烯基] -4-乙烯基环戊烯和(+)-(3 R 4 S)-3-[(1 Z)-1,3-丁二烯基] -4-乙烯基环戊烯。该策略涉及环饱和信息素类似物(+)- 8a和(-)- 8b的酶引发不对称合成,以及随后的催化氢化为手性环烷烃9a和9b,这两个字母中只有一个字母自然信使(+)- 1或(+)- 2。生物活性分析证明,这些1或2的对映体是海藻紫丁香皮,多刀属和绒球雄性配子的特征信息素。
