A hydroxy-1-alkyne is reacted with a tin hydride compound, and the obtained (E,Z)-hydroxyvinylstannanes are separated to give the (E)-substance which is further converted to a vinylcopper complex shown by
followed by the conjugate addition reaction with an &agr;, &bgr;-unsaturated cyclopentenone, and the deprotecting reaction is subsequently carried out to prepare a prostaglandin or an intermediate of prostaglandins easily, efficiently and industrially favorably.
一种羟基-1-炔与锡氢化合物反应,得到(E,Z)-羟基乙烯基锡烷,分离出(E)-物质,然后将其进一步转化为乙烯基铜配合物,随后与α,β-不饱和环戊酮进行共轭加成反应,并随后进行脱保护反应,以便轻松、高效、工业上有利地制备前列腺素或前列腺素中间体。
