A Practical and Scaleable Synthesis of 1R,5S-Bicyclo[3.1.0]hexan-2-one: The Development of a Catalytic Lithium 2,2,6,6-Tetramethylpiperidide (LTMP) Mediated Intramolecular Cyclopropanation of (R)-1,2-Epoxyhex-5-ene
摘要:
An efficient synthesis of 1R,5S-bicyclo[ 3.1.0] hexan-2-one from (R)-1,2-epoxyhex-5-ene is described. Development of a catalytic intramolecular cyclopropanation of (R)-1,2-epoxyhex-5-ene gives the key homochiral bicycle[ 3.1.0] hexan-1-ol, which is then oxidized to the desired ketone. This process has been successfully demonstrated on a multi-kilogram scale.

Studies on the Friedel–Crafts reaction between carbonyl bicyclic cyclopropane and electronic-rich aromatic systems were conducted. Lewis acid and iminium cationic activation methods were examined. It was found that the cyclopropane ring-opening was highly dependent on the nature of the counter nucleophile as well as the activation method.
