A Two Step Synthesis of 1,2,3-Substituted Pyrroles
摘要:
A method for preparing substituted pyrroles 3a-g in two steps from dihydrofurans 2a-b which were synthesized from alpha,alpha'-diazocarbonyl derivatives 1a-b was developed. The relevance of this research work lies in the easiness of preparing the substituted dihydrofurans and transforming them into pyrroles under mild conditions.
