13Z)-hexadecadienal (1), (11Z,13Z)-hexadecadienol (2), (11Z,13Z)-hexadecadien-1-yl acetate (3), and (Z)-13-hexadecen-11-ynal (4) from commercially available starting material 10-bromo-1-decanol are reported. These (Z,Z)-dienes and conjugated en-yne moieties are common in sex pheromone and attractant components for many Notodontide insect pests. The synthetic scheme, using the C10 + C3 + C3 strategy, was mainly
(11Z,13Z)-十六碳二烯醛 (1)、(11Z,13Z)-十六碳二烯醇 (2)、(11Z,13Z)-十六碳二烯-1-乙酸酯 (3) 和 (Z)-13-十六碳烯-11 的合成报道了来自市售起始原料10-溴-1-癸醇的-ynal (4)。这些 (Z,Z)-二烯和共轭烯炔部分在许多锯齿象害虫的性信息素和引诱剂成分中很常见。该合成方案采用C10+C3+C3策略,主要基于三个关键步骤:锂炔烃低温烷基化、醛与丙叉三苯基正膦的顺维蒂希烯化以及炔烃的硼氢化-质子解。该合成路线通过八步顺序提供了(11Z,13Z)-十六碳二烯醛(1),总产率为23.0%,醇(2),总产率为21.9%,乙酸酯(3),总产率为21.4%,以及(Z)-13-十六碳烯-11-炔醛(4),总产率为34.7%。这种简单的策略为实现锯齿象害虫关键性信息素的合成提供了一种新方法。
