Laser synthesis: A solvent-free approach for the preparation of phenylthiazolo[5,4-: B] pyridine derivatives
We describe here a rapid and straightforward solvent-free method to access phenylthiazolo[5,4-b]pyridines using a Nd-YAG laser NANO-NY81-10 (λ = 355 nm, 10 Hz pulse frequency; 8 ns pulse duration). This newly presented method successfully brings several improvements to the laser assisted synthesis of N,S-heterocycles. We are able to provide a solvent-, metal- and base-free method with good yield and a substantial reduction in reaction time. This journal is
A facile synthesis of 2-aminothiazolo[5,4-b]pyridines and2-aminobanzoxazoles via cyclization of thioureas
2-Aminothiazolo[5,4-b]pyridines and 2-aminobenzoxazoles havebeen synthesized from 2-hydroxy-3-thioureidopyridine and 2-hydroxy-3-thioureidobenzene respectively via acid catalyzed cyclization, which were prepared by the reaction of isothiocyanates with 2-h
