Abstract
The bromine atom in diethyl 2-acetamido-6-bromoazulene-1, 3-dicarboxylate (I) is as reactive toward the anionoid reagents as in diethyl 6-bromoazulene-1, 3-dicarboxylate. Twentyseven 6-substituted azulene derivatives have been synthesized from I by the nucleophilic substitution reaction. On one of them, diethyl 2-acetamido-6-diethylaminoazulene-1, 3-dicarboxylate, the removal of the 2-acetamido group has been carried out, giving diethyl 6-diethylaminoazulene-1, 3-dicarboxylate.
