Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranylmethyl)-1,2,3-triazoles and Alkanenitriles

Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranylmethyl)-1,2,3-triazoles and Alkanenitriles
New reactions for the transformation of 1-(oxiranylmethyl)-1,2,3-triazoles into 2-(oxiranylmethyl)-1,2,3-triazoles or alkanenitriles were established. Successive treatment of the substrate with triflic acid and t-BuOH afforded 4,6-dihydro-5-hydroxy-1,3a,6a-triazapentalene derivative.

ALKYLTHIOBENZOTHIAZOLES DECORATED WITH 1,2,3-TRIAZOLE

Vìsnik Dnìpropetrovsʹkogo unìversitetu. Serìâ Hìmìâ
Triazole and its hybrid derivatives exhibit a range of biological activities, that is why the synthesis of hybrid heterocycles that contain triazole and benzothiazole rings is relevant. The aim of the current study is the investigation of the use of terminal butynyl and pentynyl thioethers of benzothiazole in the copper catalytic reaction of 1,3 ...
