Synthesis and spectroscopic studies of new bile acid derivatives linked by a 1,2,3-triazole ring
摘要:
A novel method for the synthesis of cholic acid derivatives has been developed using 'click chemistry'. Intermolecular 1,3-dipolar cycloaddition of the propargyl ester and azide groups of 3 alpha-azidoacetoxy-7 alpha,12 alpha-diformyloxy-5 beta-cholan-24-oate gave a new dimer and oligomer linked by a 1,2,3-triazole ring. The structures of the products were confirmed by spectral (H-1 NMR, C-13 NMR, and FT-IR) analysis, mass spectrometry and PM5 semiempirical methods. Estimation of the pharmacotherapeutic potential has been accomplished for the synthesized compounds on the basis of Prediction of Activity Spectra for Substances (PASSs). (C) 2011 Elsevier Ltd.
