Synthesis of Thiazolo[2,3‐c]‐s‐triazoles Using Poly[(4‐diacetoxyiodo)styrene]
摘要:
Arenecarbaldehyde-4-arylthiazol-2-ylhydrazones underwent ring closure with poly[(4-diacetoxyiodo) styrene] (PSDIB) to 3,5-diarylthiazolo[2,3-c]-s-triazoles in dichloromethane.
Study of Oxidative Cyclization Using PhI(OAc)2 in the Formation of Benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles and Related Heterocycles – Scope and Limitations
the synthesis of benzo[4,5]thiazolo[2,3- c ][1,2,4]triazoles and related heterocycles under mild conditions was herein developed. The key step of this transformation is an oxidative cyclization employing PhI(OAc) 2 as reagent. Scope and limitations (group functionality tolerance and sterics) were studied showing the robustness of the present methodology which can be used as potential access to new fused

The synthesis of 3,5-diarylthiazolo[2,3-c]-s-triazoles (3a-f) has been accomplished by using a new method involving oxidation of arenecarbaldehyde-4-arylthiazol-2-ylhydrazones (2a-f) with iodobenzene diacetate (IBD) in dichloromethane by intramolecular cyclization in high yields.
