supporting information; experimental part, p. 1648 - 1651 (2011/08/10)
This is the first report of a facile synthesis of thiazolines and thiazines from a self-catalyzed, water assisted tandem S-alkylation-cyclodeamination reaction of thioamides/haloamines. The reaction is clean and efficient with simple product work-up, and is applicable to a variety of substrates.

Syntheses and evaluation of pyrrolidin-2-imines and 1,3-thiazolidin-2- imines as inhibitors of nitric oxide synthase (NOS) are discussed. An extensive SAR was established for pyrrolidin-2-imines class of compounds. The amidines came out as the most potent inhibitors in addition to displaying selectivity.

, p. 1382 - 1388 (2007/10/03)
The opening of the thiazoline ring upon the action of amino alcohols was studied. The effects of the reagent ratio and structures of the heterocycles and amino alcohols on aminolysis were investigated. A new method was developed for the preparative synthesis of a series of N′-(hydroxyalkyl)-2-guanidinoalkanethiols.
INTRAMOLECULAR CYCLIZATION OF GUANIDINOALKANETHIOLS IN AQUEOUS SOLUTION

, p. 1262 - 1266 (2007/10/02)
We have demonstrated the basic possibility of cyclizing guanidinoalkanethiols of different structure to thiazolines and thiazines.The rate of reaction depends on the pH of the medium.The concentration of buffer and the addition of heavy water and α-D,L-alanine have virtually no effect on the rate of reaction.
