Enol phosphinates and phosphonates can be readily prepared from simple lactams in high yields and are both stable and storable. Both these substrates can be employed successfully in homogeneous Suzuki-Miyaura and Stille cross-couplings protocols. Additionally, the phosphonate group can be immobilised on a phenol-on-polystyrene resin and utilised in a simple diversity linker strategy in which the coupled
烯醇次膦酸酯和膦酸酯可以容易地由简单的内酰胺以高收率制备,并且既稳定又可储存。这两种基材均可成功用于均质的Suzuki-Miyaura和Stille交叉偶联方案中。另外,膦酸酯基团可以固定在聚苯乙烯上的苯酚上,并用于简单的多样性接头策略中,其中在铃木-宫浦交叉偶联条件下将偶联产物从树脂上裂解下来。 内酰胺-芳基硼酸-锡烷-铃木-宫浦偶联-Stille偶联-树脂结合的烯醇次膦酸酯
