An intermolecularhydroamination of allenamides with arylamines has been achieved under mild Au(I) catalysis conditions delivering allylamino E-enamides stereoselectively and in high yield. The reaction is made possible via a convenient method for conjugated N-acyliminium formation.
An atom-economic method of preparing allylic sulfones via hydrosulfonylation of allenes with sulfinic acids under Pd(0)-catalysis was reported. This process has a high degree of regio- and stereoselectivity, and provides the target product with a moderate to excellent yield. A wide range of nitrogen- or oxygen-containing linear E-allylic sulfones have been synthesized. With the support of experimental
Photocatalytic selective synthesis of (<i>E</i>)-β-aminovinyl sulfones and (<i>E</i>)-β-amidovinyl sulfones using Ru(bpy)<sub>3</sub>Cl<sub>2</sub> as the catalyst
Selectively producing a variety of valuable compounds using controlled chemical reactions starting from a common material is an appealing yet complex concept. Herein, a photocatalytic approach for the selective synthesis of (E)-β-aminovinyl sulfones and (E)-β-amidovinyl sulfones from allenamides and sodium sulfinates was established. This reaction exhibits the traits of an eco-friendly solvent and

Abstract A novel and highly efficient heterogeneous gold(I)-catalyzed hydroamination of allenamides with arylamines has been developed that proceeds effectively undermildconditions and offers a general and practical route for the synthesis of allylamino E-enamides with good to excellent yields and high stereoselectivity. The supported gold(I) catalyst can be reused at least seven times without any
