Facile construction of 1,3-dienes building upon cross-electrophile coupling of two open-chain vinyl halides is disclosed in this work, showing moderate chemoselectivities between the terminal bromoalkenes and internal vinyl bromides. The present method is mild and tolerates a range of functional groups and can be applied to the total synthesis of a tobacco fragrance solanone.

This paper describes the catalytic asymmetric diamination of alkyl dienesusing 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) 和手性亚磷酰胺配体存在下使用N , N '-二叔丁基噻二氮丙啶 1,1-二氧化物催化不对称二烯二胺化,以高产率和高 ee 得到环状磺酰胺。该二胺化也适合克级规模。
