Sodium carbonate mediated regioselective synthesis of novel N-(hydroxyalkyl)cinnamamides
摘要:
A synthetic protocol for the direct synthesis of N-(hydroxyalkyl)cinnamamides from cinnamates and aminoalcohols in the presence of sodium carbonate as the base is presented. A wide variety of N-(hydroxyallcyl)cinnamamides were isolated in up to 99% yields. The reaction is highly regioselective and yields only N-acylated products by 1,2-addition of aminoalcohols to cinnamates. (C) 2013 Elsevier Ltd. All rights reserved.
A number of novel styryl epoxides, N‐substituted‐styryl‐ethanolamines, N‐mono and N,N′‐bis‐(2‐hydroxyethyl)‐cinnamamides ‐ analogues to the known radiosensitizers RSU‐ 1069, pimonidazole and etanidazole ‐ display selective hypoxicradiosensitizing activity. The styryl group, especially when substituted by electron withdrawing groups, was found to be bioisosteric to the nitroimidazolyl functionality
