cross-coupling of (Z)-β-halostyrenes with sodiumsulfinates in the presence of PPh3 and Na2CO3 at reflux in good yields is reported. The stereocontrolled cross-coupling process provides a series of sulfonylmethyl (Z)-stilbenes. A synthesis of tamoxifen was studied.

摘要 报道了在PPh 3和Na 2 CO 3的存在下,Pd(OAc)2催化的(Z)-β-卤代苯乙烯与亚磺酸钠的脱硫交叉偶联,收率很高。立体控制的交叉偶联过程提供了一系列磺酰基甲基(Z)-苯乙烯基苯甲酸酯。研究了他莫昔芬的合成。 报道了在PPh 3和Na 2 CO 3的存在下,Pd(OAc)2催化的(Z)-β-卤代苯乙烯与亚磺酸钠的脱硫交叉偶联,收率很高。立体控制的交叉偶联过程提供了一系列磺酰基甲基(Z)-苯乙烯基苯甲酸酯。研究了他莫昔芬的合成。
