A method for converting C–H to C–O bonds through oxidative cyclization of carboxylic acids to generate lactone products is described. The reaction employs catalytic amounts of Cu­(OAc) 2 and potassium persulfate as the terminal oxidant and is performed open to air in an aqueous acetic acid solvent system. Preliminary mechanistic studies suggest that …

Shyam Sathyamoorthi of the University of Kansas showed that the epoxide 1 could be cyclized to the differentially-protected triol 2 (Org. Lett. 2022, 24, 939. DOI: 10.1021/acs.orglett.1c04310). David J. Aitken of the Université Paris-Saclay assembled the ester 5 by adding the protected cyanohydrin 4 to the α-amino aldehyde 3 (Org. Biomol.Shanker Sathyamoorthi. Producer: Flashback.

Introduction A detailed understanding of the mechanisms of reactions that promote C–H bond functionalization is important for the continued advancement of these technologies. 1–5 We recently reported a copper-catalyzed oxidative cyclization of aliphatic and aromatic carboxylic acids using potassium persulfate (K 2 S 2 O 8) as the terminal oxidant (). 6 The reaction is performed open to air ...To our delight (and perhaps some relief), the sulfamate-tethered aza -Wacker cyclization of 10 afforded oxathiazinane 11 in synthetically useful yields and as a single diastereomer. We anticipate that 11 will serve as a key synthon for future elaboration into C4- epi -Bactobolin. Scheme 3.Shyam Sathyamoorthi, Shibdas Banerjee.

It was found to be effective for a wide variety of secondary and tertiary allylic alcohol substrates bearing aryl, alkyl, and cyano substituents. Two general reaction types were found which gave high levels of product selectivity: those driven by formation ...
