Synthetic studies towards the total synthesis of discorhabdin C
Two synthetic approaches towards the total synthesis of discorhabdin C (3) are described. The general strategy for construction of azacarbocyclic spiro dienone system is to employ an intramolecular para-phenolic alkylation ...
Total synthesis of (-)-hapalindole G: A novel tin-mediated indole synthesis
The first total synthesis of ($-$)-hapalindole G, a member of novel chlorine- and isonitrile-containing hapalindoles from the cultured cyanophyte Hapalosiphon fontinalis, is accomplished. Our 21-step synthesis of ...
Syntheses, bioactivities and conformations of peptidomimetics containing 2,3-methanoamino acids
Asymmetric syntheses of E- and Z-2,3-methanomethionine (ie E- and Z-cyclo-Met), protected Z-2,3-methanoarginine, and Z-2,3-methanoaspartic acid derivatives have been developed. These functionalized 2,3-methanoamino acids ...
Thermolysis and photolysis of bifunctional initiators: Free radical centers beta to the azo, azoxy and perester groups
Peresters $\beta$ to azo or azoxy groups are potentially interesting bifunctional initiators. They decompose thermally at essentially the same rate as the analogous simple perester. It follows that decomposition occurs ...
Transition metal-catalyzed hydroboration
Model studies on rhodium catalyzed hydroborations of sterically unbiased alkenes with catecholborane provided evidence for the role of d$\pi$-p$\pi$ bonding in these transformations. Catalyzed hydroborations of ...
