We found that the combination of Ph3P and TiCl4 was the excellent promoter for reductive Mannich-type reaction of S-2,4,6-triisopropylphenyl 2-bromopropanethioate with several imines and that the corresponding products were obtained in good yields with high anti-selectivity.
我们发现,Ph 3 P和TiCl 4的组合是S -2,4,6-三异丙基苯基2-溴丙烷硫酸酯与几种亚胺的还原曼尼希型反应的极好促进剂,并以高收率和高收率获得了相应的产物。反选择性。
