An efficient and convenient synthesis of enantiopure 4-(t-butyldimethylsilyloxy)-cyclohex-2-en-1-one: A formal synthesis of (±)-mesembranol

Inexpensive enantiopure (+)-limonene oxide 1 is converted to 4-(R)-(t-butyldimethylsilyloxy)-cyclohex-2-en-1-one 2a. All isolated intermediates can be distilled obviating the need for chromatography. With 2a,b in hand, a formal synthesis of (±)-mesembrano

Chiral and stereoselective total synthesis of (-)-mesembranol starting from D-glucose

A chiral synthesis of the Sceletium alkaloid (-)-mesembranol 1 is described. The cyclohexane ring in 1 is prepared in an optically active form from D-glucose using Ferrier's carbocyclisation, and the critical stereochemistry of the quaternary carbon in 1 is constructed stereoselectively via chirality transfer by way of Claisen rearrangement of the cyclohexenol derivative 14a. The perhydroindole skeleton in 1 is effectively generated by intramolecular aminomercuriation of the amino-olefin 18.
