A robust, chemoselective direct condensation/cyclization of thioureas and amino alcohols is described. Employing a bench-stable Vilsmeier reagent, methoxymethylene- N, N -dimethyliminium methyl sulfate, the selective in situ activation of alcohols is achieved with high efficiency and broad functional-group tolerance. The reversible interaction of the Vilsmeier reagent with substrate was key to the success of this activation strategy.

The ring-opening polymerisation of lactide by a range of aminooxazoline and amino-thiazoline catalysts is reported. The more electronrich derivatives are demonstrated to be the most highly active and polymerisation is well controlled, as evidenced by the

A series of 2-phenylaminothiazolines have been prepared from the corresponding N-(2-hydroxyethyl)-N'-phenylthioureas under mild reaction conditions using either thio-CDI (1,1'-thiocarbonyldiimidazole) or CDI (1,1'-carbonyldiimidazole) to promote the cycli

p-Toluenesulfonyl chloride (TsCl)/NaOH has been introduced as reagent combination for the synthesis of 2-amino-oxa- or 2-amino-thiazolidines from N-(2-hydroxyethyl)-thioureas, but its general application in heterocycle synthesis has not been investigated. In this paper the convenient and efficient synthesis of a variety of 2-amino-substituted 1-aza 3-(aza, oxo or thio) heterocycles of different substitution and ring sizes is described. The application of polymer-supported TsCl facilitates work-up and renders the reaction conditions very suitable for parallel or robot synthesis. Graphical Abstract

2-Phenylaminothiazolines 3 were synthesized from N-(2-hydroxyethyl)-N'-phenylthioureas 2 by a one-pot reaction using p-toluenesulfonyl chloride (TsCl) and NaOH or Et3N.
