A NEW SYNTHETIC ROUTE TO α-DAMASOONE

Institute of Materia Medica Chinese Academy of Sciences Beijing 100050

Received Date: 13 December 1991

A new synthetic route to α-damascone (4) starting from citral is described-The synthesis features allylatioa of α-cyclocitral (1) with allylic bromide in the presence of tin powder to give the crucial intermediate 1-(2',6',6'-trimethylcyclo-hexen-2'-yl)-3-buten-1-ol (2a) and (2b) in a combined yield of 70%.
