Total synthesis of optically pure spatol (+)-1 was achieved by employing asymmetric (2+2) photocycloaddition of the optically pure 12 with cyclopentenone ethylene ketal.The two major photocycloadducts 14, 15 were separately converted into the cis,anti,cis-tricyclo2,6>decane 9 and then to the sulfonium 11.Coupling of 11 through ylide with optically active epoxyaldehyde 24 provided optically pure 1 with definite absolute configuration.
