Enantiospecific synthesis of (+)-trans-α-himachalene via an intramolecular type II carbonyl ene reaction

Enantiospecific synthesis of (+)-trans-α-himachalene starting from (R)-carvone is described. An intramolecular type II carbonyl ene reaction has been employed as the key step for the construction of the bicyclo[5.4.0]undecane ring system.

Enantiospecific first total synthesis of (+)-trans-α-himachalene

An enantiospecific first total synthesis of (+)-trans-α-himachalene, one of the eight male specific sesquiterpenes isolated from the crucifer flea beetle Phyllotreta cruciferae, starting from the readily and abundantly available monoterpene, (R)-carvone,

Carbanion cyclisation of esters. Part 2: Enantiospecific construction of the tricyclic framework of the marine sesquiterpenes, spirodysins

Enantiospecific construction of the bicyclo[4.3.0]nonan-8-one 17 employing a lithium and liquid ammonia mediated carbanion cyclisation of the δ-methyl-δ,ε-unsaturated ester 13, and its elaboration to the tricyclic framework of the marine sesquiterpenes sp
