[EN] SMALL MOLECULE ACTIVATORS OF NICOTINAMIDE PHOSPHORIBOSYLTRANSFERASE (NAMPT) AND USES THEREOF [FR] ACTIVATEURS À PETITES MOLÉCULES DE NICOTINAMIDE PHOSPHORIBOSYLTRANSFÉRASE (NAMPT) ET LEURS UTILISATIONS
Sulfoxonium ylides as carbene precursors couple smoothly with thioureas in the presence of 5 mol% of rhodium(II) acetate dimmer via carbenoid insertion to afford the corresponding 2-aminothiazoles with high chemoselectivity, providing a facile and efficient approach to access a variety of 2-aminothiazole derivatives with good functional groups tolerance.
In this study, a series of novel N-(4-phenylthiazol-2-yl)-cinnamamide derivatives (7a–8n) were synthesized and evaluated for their anti-proliferative activities in vitro.

A range of heterocycles, namely thiazoles, imidazoles, imidazopyridines, thiazolidines and dimethoxyindoles, have been synthesised directly from alkenesvia a two-step ketoidoination/cyclisation protocol. The alkene starting materials are themselves readily accessible using many different and well-established approaches, and allow access to a variety of heterocycles with excellent yields and regioselectivity.
