A straightforward metal-free synthesis of 2-substituted thiazolines in air
A base-catalysed procedure for the synthesis of 2-substituted thiazolines from nitriles and cysteamine hydrochloride under solvent-free conditions is presented. This straightforward approach allows high conversion for a broad range of nitriles and an easy

DDQ-induced dehydrogenation of heterocycles for c-c double bond formation: Synthesis of 2-thiazoles and 2-oxazoles
Strong as an Ox: 2-Thiazoles and 2-oxazoles are formed by oxidation of 2-thiazolines and 2-oxazolines without requiring substituents at the C4 and C5 positions. DDQ plays an important role as the oxidant in this transformation and metal is unnecessary. This general procedure shows good functional group tolerance and provides a wide variety of 2-thiazoles and 2-oxazoles in moderate to excellent yields.
Tribromomelamine: A novel and efficient catalyst for the synthesis 2-arylthiazolines under solvent-free conditions
A novel procedure for the synthesis of 2-arylthiazolines through one-pot condensation of of nitriles with 2-aminoethanethiol in the presence of tribromomelamine as catalyst under solvent-free conditions is described.

Solvent-free tandem synthesis of 2-thiazolines and 2-oxazolines catalyzed by a copper catalyst
Tandem reactions of nitriles with 2-aminoethanethiol hydrochloride or amino alcohols in the presence of a catalytic amount of cupric methacrylate (Cu II2L4, L = methacrylate) were employed to prepare 2-thiazolines and 2-ox
Facile Syntheses of Oxazolines and Thiazolines with N-Acylbenzotriazoles under Microwave Irradiation
Microwave reactions of 2-amino-2-methyl-1-propanol (2) or 2-aminoethanethiol hydrochloride (4) with readily available N-acylbenzotriazoles 1a-j in the presence of SOCl2 produced 2-substituted 2-oxazolines 3a-j in 84-98% yields and 2-substituted

Research on radioprotective agents: Δ-2 Thiazolines and homologous derivatives
Compounds derived from Δ-2 thiazoline, Δ-2 thiazolinium iodoalkylate and 4,5-dihydro-1,3 thiazine have been prepared and evaluated as potential antiradiation agents in mice. They generally have a low toxicity and significant radioprotective activity.
