Copper-catalyzed cycloisomerization of unactivated allene-tethered O-propargyl oximes: A domino reaction sequence toward the synthesis of hexahydropyrrolo[3,4- b]azepin-5(4 H)-ones

A novel copper-catalyzed cycloisomerization of unactivated allene-tethered O-propargyl oximes has been developed for the synthesis of hexahydropyrrolo[3,4-b]azepin-5(4H)-ones. This one-pot domino reaction proceeds via a [2,3]-sigmatropic rearrangement, a

Thiocyanate radical mediated dehydration of aldoximes with visible light and air

We developed a new means of activating aldoximes by an in situ generated thiocyanate radical from ammonium thiocyanate and molecular oxygen at room temperature. With a catalytic amount of organic dye aizenuranine as the photocatalyst, the dehydration of aldoximes proceeds smoothly under visible light irradiation, providing a simple to handle, excellent functional group tolerance, and metal-free protocol for a wide range of nitriles.

Synthesis of α-methylene-γ-butyrolactones: Ru-catalyzed cyclocarbonylation of allenyl aldehydes and allenyl ketones

An efficient route to α-methylene-γ-lactones involves the Ru-catalyzed [2+2+1] cycloadditions of allenyl aldehydes and ketones with CO (see scheme; n = 1, 2; R = H, CH3; X = NTs, O, C(CO2Et)2; Ts = toluene-4-sulfonyl). The
