Total synthesis and absolute configuration of malyngamide W

A concise enantioselective synthesis of malyngamide W (1) and its 2′-epimer was described. The strategy was based on three key steps: (1) ozonolysis of compound 11 which was derived from (R)-(-)-carvone 8, followed by copper-iron-catalyzed rearrangement to give the key cyclohex-2-enone intermediate 5, (2) Nozaki-Hiyama-Kishi coupling reaction between aldehyde 4 and iodide 14 to afford alcohol 3, and (3) asymmetric (R)-CBS reduction of the ketone functionality in compound 21 to establish the C-2′ chiral center in the target compound 1. The absolute configuration of malyngamide W (1) was thus confirmed via the synthesis of 1 and 2′-epi-1.

Total synthesis of malyngamides K, L, and 5″-epi-C and absolute configuration of malyngamide L

An accelerated, enantioselective, and general synthetic route to a class of malyngamides, K (1), L (3), and 5″-epi-C (4), bearing a cyclohexenone ring or a heavily oxygenated six-membered ring and a vinyl chloride structural motif was developed. The key s

Bryostatin: A novel asymmetric synthesis of the C27-C34 fragment starting from (R)-carvone as chiral template

(R)-Carvone is a suitable chiral template for the synthesis of differently protected (4S,6R,7R)-trihydroxy-1-octyne derivatives, the C27-C34 fragment of bryostatins. Also other potentially interesting chiral building blocks are described.

(R)-Carvone as chiral template for the synthesis of some polyols

Some (4S,6R,7R) 4,6,7-trihydroxyheptyl derived building blocks have been obtained from (R)-carvone as the chiral template.A key-step is the Baeyer-Villiger oxidation of a suitable intermediate.

Thiol/Diselenide Exchange for the Generation of Benzeneselenolate Ion. Catalytic Reductive Ring-Opening of α,β-Epoxy Ketones

In the presence of N-acetylcysteine sodium salt, benzeneselenolate ion was generated in situ from diphenyl diselenide via thiol/diselenide and thiol/selenenyl sulfide exchange in aqueous methanol under mild conditions.Benzeneselenolate ion thus formed was efficiently alkylated and arylated to afford alkyl phenyl selenides and aryl phenyl selenides, respectively. α,β-Epoxy ketones were catalytically reduced by benzeneselenolate ion to afford β-hydroxy ketones (aldols) in good yields.The stereospecificity of the reaction was demonstrated in the preparation of optically active β-hydroxy ketones from chiral α,β-epoxy ketones.
