A transition-metal-catalyzed approach to cyclic α-thiophosphonates is reported. This strategy incorporates both a Rh2(OAc)4-catalyzed [2,3]-sigmatropic rearrangement of intermediate sulfur-ylides generated from α-diazophosphonates and a ring-closing metathesis (RCM) of the resulting α-thiophosphonates 2 a - c to yield functionalized cyclic α-thiophosphonates 4 a - c.
报告了一种过渡金属催化的环状δ±-硫代磷酸酯的方法。该策略包括 Rh2(OAc)4 催化的δ-二氮膦酸盐生成的中间硫酰基的[2,3]-三向异性重排,以及由此生成的δ-硫代磷酸盐 2 a - c 的闭环偏析 (RCM),从而生成官能化的环状δ-硫代磷酸盐 4 a - c。
