M. Carda et al., SYNTHESIS OF (E)-2,6-DIMETHYL-6-HYDROXYOCTA-2,7-DIENOIC ACID AND THE CORRESPONDING AMIDE (ACACIALACTAM) IN OPTICALLY-ACTIVE FORM, Tetrahedron, 51(9), 1995, pp. 2755-2762
The total synthesis of the title compounds in optically active form fr
om geraniol as the starting material is described. The physical and sp
ectral properties of the synthetic amide are identical with those of t
he natural compound acacialactam, this fact confirming that the struct
ure proposed for the latter compound is not correct. The configuration
of the single stereogenic carbon atom in the natural amide is shown t
