This paper describes the catalytic asymmetric diamination of alkyl dienes using N,N'-di-tert-butylthiadiaziridine 1,1-dioxide in the presence of Pd(0) and a chiral phosphoramidite ligand to give cyclic sulfamides in high yield and high ee. The diamination is also amenable to gram scale.
本文描述了在 Pd(0)和手性膦酰胺配体存在下,使用 N,N'-二-叔丁基亚磺酰基二氮唑 1,1-二氧化物催化的二烯基的不对称二氨基化反应,以高产率和高对映选择性得到环状磺酰胺。该二氨基化反应也适用于克级规模。
