Herein, we describe the photochemical O?H functionalization reaction of acidic alcohols with cyclic diazoamides. We studied the O?H functionalization reaction of different fluorinated and non-fluorinated alcohols to give the corresponding ether products in high yields (43 examples, up to 97% yield). Furthermore, we performed studies to evaluate a photoexcited proton transfer reaction pathway in comparison to classic carbene transfer reactions. (Figure presented.).

A gold-catalyzed dimerization of 3-diazooxindoles was developed, delivering isoindigos as products. The reaction shows broad substrate scope and functional group tolerance by affording various substituted isoindigos. Moreover, the method also exhibited high efficiency on a gram-scale reaction.

(Chemical Equation Presented) A new and efficient synthetic route to chiral 3-substituted hexahydropyrroloindoline 18 possessing absolute configurations in accordance with indole alkaloids has been developed from readily available L-tryptophan. The key step relies on the one-pot cascade reaction of oxazolidinone 17 with diazoester, which proceeds through intermolecular cyclopropanation, ring opening, and cyclization.
