Arenesulfonamides, sulfamide, and cyanamide are efficiently allylated using allylic carbonates under Pd(0)-catalysis. N-Arenesulfonyl-2,5-dihydropyrroles are obtained by ruthenium-mediated ring closing metathesis of the corresponding N-diallylated compounds. A stereochemical study of the reactions of ethyl cis-(5-methyl-2-cyclohexenyl) carbonate with 2,4,6-triisopropylphenylsulfonamide was performed
在Pd(0)催化下,使用烯丙基碳酸酯可将烯丙基磺酰胺,磺酰胺和氰胺有效地烯丙基化。N-戊烯磺酰基-2,5-二氢吡咯通过相应的N-二烯丙基化的化合物的钌介导的闭环复分解而获得。对碳酸顺式-(5-甲基-2-环己烯基)酯与2,4,6-三异丙基苯基磺酰胺的反应进行了立体化学研究,发现双齿膦完全保留了构型。
