The first examples of the synthesis of 1,3-dienyl sulfoxides by Heck reactions are described. Both racemic and enantiomerically pure exocyclic 1-p-tolylsulfinyl-1,3-dienes 1 are readily prepared by the intramolecular Heck reaction of their corresponding vinyl iodides in the presence of Pd(OAc)2 as catalyst and Ag2CO3 as base.
描述了通过Heck反应合成1,3-二烯基亚砜的第一个实例。通过在Pd(OAc)2作为催化剂和Ag 2 CO 3作为碱的存在下,通过其相应的乙烯基碘的分子内Heck反应,可以容易地制备外消旋和对映体纯的环外1-对甲苯亚磺酰基-1,3-二烯1。
