One-Pot Multicomponent Synthetic Route for New Quinolidinyl 2,4-Thiazolidinediones
Jyotirling R. Mali,Manisha R. Bhosle,Shital R. Mahalle,Ramrao A. Mane 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.7
A convenient one-pot condensation route has been developed for obtaining 5-[(2-(piperidin-1-yl) quinolin-3-yl)methylene]-2,4-thiazolidinediones using multicomponents, 2-chloro-3-formyl quinolines, piperidine, 2,4-thiazolidinedione and safer medium/mediator, polyethylene glycol-400.

A convenient synthetic route has been developed to synthesize 5-(4-((2-phenylthiazol-4-yl) methoxy)phenyl)-3-(4-sustituted phenyl)pyrazolines (5a-f) and 5-(4-((2-phenylthiazol-4-yl)methoxy)phenyl)-3-(4-substituted phenyl)isoxazolines (6a-f) starting from 2-phenyl-4-chloromethylthiazole (1). The chloromethylthiazole (1) was first condensed with 4-hydroxy benzaldehyde (2) for obtaining 4-((2-phenylthiazol-4-yl)methoxy)benzaldehyde (3). Claisen-Smidth condensation of 4-((2-phenylthiazol-4-yl)methoxy)benzaldehyde (3) and acetophenones has been carried in alkaline alcohol and obtained 3-(4-((2-phenylthiazol-4-yl)methoxy)phenyl)-1-(4-substituted phenyl)prop-2-en-1-ones (4a-f). The cyclocondensation of 2-propen-1-ones has been first time carried separately with hydrazine hydrate and hydroxylamine hydrochloride in aqueous micellar tetradecyltrimethylammonium bromide (TTAB) medium for getting the titled heterocycles with good to excellent yields.

Synthesis of 2-Arylbenzothiazoles Catalyzed by Biomimetic Catalyst, β-Cyclodextrin
Balaji S. Londhe,Umesh R. Pratap,Jyotirling R. Mali,Ramrao A. Mane 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.8
Cyclocondensation of 2-aminothiophenol and aryl/heteryl aldehydes has been carried using biomimetic catalyst, β-Cyclodextrin in water and obtained 2-aryl/heteryl benzothiazoles with better to excellent yields. This biomimetic catalyzed route is simple, economic, and environmentally benign.
