A variety of biologically and synthetically useful 3-alkenyloxindoles were rapidly synthesised via an SN2′-type allylic substitution reaction of isatin-derived Morita–Baylis–Hillman carbonates with sodium sulfinates. The syntheses were conducted under catalyst-free reaction conditions and good to excellent product yields (up to 96%) and Z/E selectivities (up to >20:1) were obtained.
A facile, atom-economical, catalyst-free protocol for the hydrosulfonation of densely functionalized alkenes with sulfinic acids in an environmentally benign solvent system at ambient temperature is described.
