3-hexadienyl)-2-vinylcyclopropane) is the specific sex attractant of several brown algae of the Australian shelf, while dictyopterene A ((+)-2; (1R, 2R)-1-((1E)-1-hexenyl)-2-vinylcyclopropane) is found as a minor constituent of the pheromone bouquets. The asymmetric synthesis of the two hydrocarbons is performed by resolution of the amides (−)-5 and (+)-5a obtained from (−)-(R)-2-phenylglycinol and racemic trans
Hormosirene((-)- 1 ;(1 R,2 R)-1-((1 E,3 Z)-1,3-己二烯基)-2-乙烯基环丙烷)是澳大利亚几种褐藻的特异性引诱剂货架,而dictyopterene A((+)- 2 ;(1 R,2 R)-1-((1 E)-1-己烯基)-2-乙烯基环丙烷)被发现是信息素束的次要组成部分。( - ) -二烃的不对称合成是由酰胺的分辨率进行5和(+) - 5a中( - ) - (获自- [R)-2-苯基甘氨醇和外消旋反式-vinylcyclopropanecarboxylic酸(外消旋- 4)在硅胶上。两种非对映异构体都是光学纯的。通过立体选择性维蒂希烯化将它们转化为标题化合物。化合物(-)- 1是通过生物学活性测定法确定的海藻剑兰生殖系统的活性交配信息素。
