Chiral synthesis of (2s,3s,7s)-3,7-dimethylpentadecan-2-yl acetate and propionate, potential sex pheromone components of the pine saw-fly neodiprion sertifer (geoff.)
A synthesis of (2S,3S,7S)-3,7-dimethylpentadecan-2-yl acetate () and propionate () is described. (2S)-2-Methyldecan-1-yl lithium () was reacted with (3S,4S)-3,4-dimethyl-γ-butyrolactone () to yield the ketoalcohol which upon Huang-Minlon reduction furnished (2S,3S,7S)-3,7-dimethylpentadecan-2-ol (). Acylations gave the esters and . The (2S)-2-methyldecan-1-yl lithium was obtained via asymmetric synthesis

All of the four possible stereoisomers of 2,3-erythro-3,7-dimethylpentadecan-2-ol 1 were synthesized by a stereospecific SN2 oxirane cleavage of (2S,3S)-2,3-epoxybutane or its antipode with lithium di[(R)- or (S)-4-methyldodecyl]cuprate. Their acetates or propionates were prepared to test their pheromone activity.
通过(2 S,3 S)-2,3-环氧丁烷或其对映体的立体特异性S N 2环氧乙烷裂解,合成了2,3-赤--3,7-二甲基十五烷基-2-醇1的所有四种可能的立体异构体。用二[(R)-或(S)-4-甲基十二烷基]铜酸锂。准备它们的乙酸盐或丙酸酯以测试其信息素活性。
