A simple synthesis of New Push-Pull substituted imidazoles by chemoselective nucleophilic attack of α-cyano epoxides
摘要:
A chemoselective reaction of amidines or guanidines with alpha- cyano epoxides leads to new 4-amino-5-carbethoxy or 4-hydroxy-5-cyano or 4-carbethoxy-5-aryl- imidazoles depending on the steric hindrance of the epoxides and on the reaction medium.
