Flexible and enantioselective access to jaspine B and biologically active chain-modified analogues thereof

Whereas the all-cis tetrahydrofuran framework of the cytotoxic anhydrophytosphingosine jaspine B is considered as a relevant pharmacophore, little is known about the influence of the aliphatic chain of this amphiphilic molecule on its activity. We developed a synthetic strategy allowing flexible introduction of various lipophilic fragments in the jaspine’s skeleton. The route was validated with two distinct approaches to jaspine B. Five chain-modified analogues were also prepared. Biological evaluation of these derivatives demonstrated a good correlation between their cytotoxicity and their capacity to inhibit conversion of ceramide into sphingomyelin in melanoma cells. A series of potent and selective inhibitors of sphingomyelin production was thus identified. Furthermore, the good overall potency of an omega-aminated analogue allowed us to dissociate of the pharmacological action of jaspine B from its amphiphilic nature.

Selective synthesis of multisubstituted olefins utilizing gem – And vic -diborylated vinylsilanes prepared by silylborylation of an alkynylboronate and diborylation of alkynylsilanes

The synthesis of a series of gem- and vic-diborylated vinylsilanes was accomplished via highly selective transition-metal-catalyzed syn-dimetalation to the alkynylmetal species. This protocol served as a general synthetic method toward regio- and stereodefined multisubstituted olefins. The key steps are the diastereoselective Suzuki-Miyaura cross-coupling reactions of gem- and vic-diborylated vinylsilanes, in which the two boron groups showed discrete reactivities to afford diverse precursors of multisubstituted olefins.

Synthesis of 2H-chromenes through the reduction of chromones with 9-BBN

Chromones were regioselectively reduced to 2H-1-benzopyrans through the 1,2-addition of 9-borabicyclo-[3.3.1]nonane. Although transition-metal complexes did not have a catalytic effect on the reaction, only by using palladium(II) chloride, could both 2H-1-benzopyran and dihydro-1-benzopyran be obtained to a similar extent. Also, the reduction of chromone using other organoboranes led not to 2H-1-benzopyran, but rather to chromanone through the reduction of only an olefin moiety.
