A convergent strategy is reported for the construction of nitrogen-containing heterocycles from common substrates: 1,4-diketones and primary amines. Indeed, by just varying the substrates, the substituents, or the heating mode, it is possible to sele

A Barbier reaction–Heck arylation sequence from α-bromomethylbutenolide to fused tri and tetracyclic lactones has been developed. The first step involving a Barbier reaction enabled installing ortho-bromoaromatics in α-ylidene γ-lactones. The la

Due to the joint presence of several functional groups, β-ethoxycarbonylatedallylphosphonates are considered as excellent precursors for the preparation of neworganophosphorus compounds. In the presentwork, we first described the use of suchphosphon
