摘要

Dariuz Ciez (Jagiellonian University, Krakow) describes in the April issue the synthesis of imidazoline-2-thiones 4 by means of a Mannich reaction of α-iminocarboxylic acid esters 2 with the enols derived from α-isothiocyanatocarboxylic esters 1. The imidazoline-2-thiones can be considered as masked 2,3-diaminosuccinic acid derivatives, which are important in certain peptidic antibiotics.
