Abstract

An expeditious solventless synthesis of novel lariat ethers using calcium oxide (CaO) via Mannich reaction are herein described. This methodology eliminates the use of excess of solvent during the course of reaction. The reaction time is brought down from hours to minutes (20-30 minutes) along with yield enhancement. The CaO powder can be reused up to three times after simple washing with acetone.
