A variety of functionalized unsymmetrical (Z) or (E)-enediynes 1 and 2 are stereospecifically prepared in good overall yield by a simple straightforward one-pot procedure from (Z) or (E)-1,2-dichloroethylene and 1-alkynes. Zinc reduction of 1 and 2 leads efficiently to pure (Z,Z,Z) and (Z,E,Z) conjugated trienes.
通过简单简单的一锅法从(Z)或(E)-1,2-二氯乙烯和1-炔烃简单立体地以良好的总收率立体定向地制备各种功能化的不对称(Z)或(E)-烯二炔1和2。1和2的锌还原可有效生成纯的(Z,Z,Z)和(Z,E,Z)共轭三烯。
