Abstract: The first Cu-catalyzed dehydrogenative C-O cyclization for the synthesis of furan-fused thienoacenes is described. A variety of heteroacenes including a thieno[3,2-b]furan or a thieno[2,3-b]furan skeleton were synthesized by intramolecular C-H/O-H coupling. The use of a… read more here.

DOI: 10.1021/acs.orglett.7b03448
Abstract: Oxidative dehydrogenative [2 + 3]-cyclization of glycine derivatives with N-sulfonylaziridines is described. A series of complex imidazolidines were produced under mild and simple reaction conditions. A mechanism involving an unusual acid-promoted auto-oxidation is proposed. read more here.
