Autor: J. H. van den Hende, J. W. Greidanus, T. Doornbos, H. C. Volger, J. F. Arens, J. Bonnema

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 75:1459-1472

From acetylenic thioethers, Grignard or lithium derivatives can be obtained, which react with carbonyl compounds to yield the expected carbinols. The reactions with carbon dioxide and ethyl chlorocarbonate also are normal. By oxidative “dimerisatio

Synthesis of 2-acyl-2-thiazolines

Autor: H. G. Peer, T. Doornbos

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 91:711-728

2-Acyl-2-thiazolines were prepared by condensation of vic-aminothiols with 2,2-dialkoxyalkanenitriles and hydrolysis of the resulting 2-(1,1-dialkoxyalkyl)-2-thiazolines. A similar route via 2-(1-hydroxyiminoalkyl)-2-thiazolines also proved successfu
