Selective deoxygenation of allylic alcohol: Stereocontrolled synthesis of lavandulol

Selective deoxygenation of allylic alcohol can be successfully carried out by the formation of alkoxyalkyl ether (EE or MOM), followed by Pd(dppe)Cl 2-catalyzed reduction with LiBHEt3. (+)-S-Lavandulol has been efficiently synthesized by the application of this protocol to the diol derived from the Pb(OAc)4-promoted oxidative ring-opening of (-)-R-carvone. This deoxygenation method is general and selective for allylic alcohols.

C45- and C50-Carotenoids, 1st Communication. Synthesis of (R)- and (S)-Lavandulol

Starting with methyl (3R)-3-hydroxybutanoate ((R)-7) and ethyl (3S)-3-hydroxybutanoate ((S)-11), respectively, (R)- and (S)-lavandulol ((R)-1 and (S)-1) were synthesized with high optical purity.The synthesized key intermediates (R)-6 and (S)-6 are suitable compounds for the synthesis of optically active acyclic C45- and C50-carotenoids.
