The Rh-catalyzed direct selectiveoxidation Heck reaction of benzamides with allylic esters has been developed for the synthesis of amides and isoquinolin-1-ones. According to the functional groups on N-atom, benzamides or isoquinolin-1-ones were synthesized under optimal reaction conditions. The ambient catalytic system has good functional group tolerance, afforded corresponding products in moderate

The cobalt catalyzed hydroaldoximation and hydrocyanooximation of unactivatedalkenes is reported. Secondary and tertiary aldoximes and oximonitriles are synthesized with excellent regioselectivity under mild conditions, and conversion of the products to valuable intermediates is documented. The reactions expand the arsenal of reductive carbon-carbon bond forming reactions as well as regioselective

It also concerns phytosanitary formulations or resin-solubilising formulations comprising at least one such furfural derivative of formula (I).
Scandium(III) triflate promoted highly selective addition of thiols to functionalizedolefins under mild conditions. The addition follows anti-Markovnikov regioselectivities, which are unusual for Lewis acids-catalyzed hydrothiolation. This reaction marks broad functional groups tolerance, which opens a beneficial synthetic route to functionalized and biologically active thio-compounds. This method
