| Abstract: | The ozonization of abienol in ethyl acetate in the presence of pyridine or in methanol followed by the reduction of the peroxides by methyl sulfide has given ambreinolide. On reduction of the peroxide products of the ozonolysis of isoabienol in methanol with potassium tetrahydroborate, the main reaction product was 15,16-bisnorlabdane-8,13,14-triol. Dimethyl sulfide first caused the rearrangement of the peroxide products of ozonization with the cleavage of the ordinary C-13-C-14 carbon bond, and then their reduction.Institute of Chemistry, Academy of Sciences of the Moldavian SSR, Kishinev.
