Stereoselective reduction of conjugated homopropargylic alcohols 1 followed by an elimination reaction, allows an efficient approach to stereodefined (E,E,E)-chlorotrienes. The interest of these chlorotrienes was illustrated by a stereocontrolled synthesis of navenone B and allE conjugated polyenes (trienes, tetraenes and hexaenes).
立体选择性还原共轭均炔丙醇1,然后进行消除反应,可以实现立体定义的(E,E,E)-氯三烯的有效方法。这些碳三烯的兴趣通过navenone B和所有E共轭多烯(三烯,四烯和己烯)的立体控制合成得到了说明。
