A straightforward strategy for synthesis of highly functionalized trifluoromethyl 2H-furans is described. The copper catalyzed method relies on a cascade cyclic reaction between enaminones and N-tosylhydrazones. This method allows the synthesis of 2-amino

A highly site-selective acyloxylation of stable enamines with PhI(OAc)2 under metal-free conditions to afford (E)-vinyl acetate derivatives in good to excellent yields is described. Depending on the judicious choice of the solvent system, either the α- or β-site-selective product could be obtained with high selectivity. For the α-site-selective product, the rearranged amide compound is obtained as the major product. This reaction proceeds under mild reaction conditions (room temperature, metal-free, and open-flask) and features a broad substrate scope.

Rh(III)-catalyzed enaminone-directed C-H coupling with α-diazo-α-phosphonoacetate has been used for the identification of fluoride-mediated dephosphonation C-C coupling reactivity for the synthesis of 4-hydroxy-1-naphthoates. Intermolecular C-C coupling of α-phosphonoacetate and benzaldehyde for (E)-selective α,β-unsaturated ester synthesis has also been achieved.

supporting information, p. 2418 - 2421 (2017/05/12)
We report herein the development of a Co(III)-catalyzed enaminone-directed C-H amidation method for synthetic access to quinolones, an important heterocyclic scaffold for diverse pharmaceutically active structures. The C-H coupling with dioxazolones and subsequent deacylation of an installed amide group allow consecutive C-N coupling generation of quinolones with wide-ranging compatible substituent patterns.
