Scandium triflate catalyzed ester synthesis using primary amides
摘要:
A scandium triflate (ScOTf)(3) catalyzed methodology has been developed to synthesize esters from primary amides. Various primary and secondary aliphatic alcohols have been shown to react in n-heptane with a range of primary amides for 24 h. (C) 2014 The Authors. Published by Elsevier Ltd.

A novel class of benzo[d][1,3]dioxol‐5‐ylmethyl alkyl/aryl amide and ester analogues of capsaicin were designed, synthesized, and evaluated for their cytotoxic activity against human and murine cancer cell lines (B16F10, SK‐MEL‐28, NCI‐H1299, NCI‐H460, SK‐BR‐3, and MDA‐MB‐231) and human lung fibroblasts (MRC‐5). Three compounds (5f, 6c, and 6e) selectively inhibited the growth of aggressive cancer
