This report discloses the deallylation of O - and N -allyl functional groups by using a combination of a Ni-H precatalyst and excess Bronsted acid. Key steps are the isomerization of the O - or N -allyl group through Ni-catalyzed double-bond migration followed by Bronsted acid induced O/N-C bond hydrolysis. A variety of functional groups are tolerated in this protocol, highlighting its synthetic value.

A variety of chromeno[4,3-c]isoxazolidines were prepared in good yields through visible light promoted Chan-Lam reaction and [3+2] cycloaddition cascade reaction in one pot. Mechanistic studies showed that visible light promoted both Chan-Lam reaction and cycloaddition. The obtained products were converted to various useful chromenone derivatives. Moreover, the reaction was easily performed at gram scales with the purification of products without column chromatography and used to efficiently synthesize estrone-derived chromeno[4,3-c]isoxazolidine.

A clean and effective method has been developed for the regioselective of O-allylation of phenol derivatives using a recyclable Cu(I)-exchanged multi-size porous material. Ease of preparation of catalyst through simple solid-state exchange and its compatibility in producing excellent amount of O-allylated products and a plausible mechanistic pathway for the regioselectivity are highlighted. This reported procedure is not requiring any external stabilizing ligand for Cu(I) species and further purification of products.
