Ultrasound-assisted addition of alcohols to N-acyliminium ions mediated by In(OTf)3 and synthesis of 1,2,3-triazoles
摘要:
An easy and mild approach using ultrasound-assisted reaction addition of alcohols to N-acyliminium ion mediated by Lewis acid, In(OTf)3, allowed the synthesis of ether pyrrolidinones; next, the products were converted to 1,2,3-triazoles using click chemistry reaction conditions. The products in both reactions were afforded in moderate to good yields. 2014 Elsevier Ltd. All rights reserved.
