Propylene carbonate is shown to be an environmentally friendly and sustainable replacement for dichloromethane and acetonitrile in proline-catalysed a-hydrazinations of aldehydes and ketones. Enantioselectivities comparable to those obtained in conve

The Cu-mediated synthesis of tetrasubstituted olefins by the addition of an acetate group and a thiolate to an unactivated internal alkyne is described. The reaction is fully stereoselective, because only the E alkene is obtained. If the alkyne is as

The synthesis of fused heterocycle-pyridinones has been achieved by oxidative coupling of N-unprotected primary heterocycle-amides with internal alkynes. The reaction, which is catalysed by Ru(II) and assisted by Cu(II), takes place through C–H and

Two processes, intra‐ and intermolecular, involving alkenes and alkynes, have been used as main synthetic tools for the synthesis and functionalization of amyriad of heterocycles, whose industrial and academic importance resides in the fact that th

A C,S-cycloaurated complex based on an ortho-substituted phosphinothioic amide framework has been synthesized in high yield through tin(IV)-Au(III) transmetalation from the corresponding chlorodimethylstannyl derivative. The latter was prepared in a

Organic syntheses based on the activation of C–H bonds catalysed by transition metals (TM) are of great interest because new pathways can be designed that were not previously available. Of the numerous TMs, ruthenium has emerged as a powerful alter
