Continuous measurement of the field strength of NHK's overseas broadcasting waves (JOB, 11.815MHz) was carried out from April, 1970, to February, 1971. The diurnal variations in field strength were not found at the equinox, but in other months the fi

Herein, we describe the first total synthesis of fomitellic acid B (2), a potent inhibitor of DNA polymerases α and β. There are two key features in this synthesis: (i) the AB ring system, with all requisite chiral centers, is stereoselectively con

Stereocontrolled synthesis of a fully functionalized AB ring moiety of fomitellic acids was accomplished. The tricyclic skeleton was stereoselectively constructed by means of titanium(III)-mediated radical cascade cyclization of epoxypolyene. The ste

A remarkable enhancement in the rate of a TiCl4-mediated stereoselective vinylogous Mukaiyama aldol reaction (VMAR) using vinylketene silyl N,O-acetal 1 was observed in the presence of water.

SmI2-mediated reductive cleavage of α-hetero substituents of α-alkyl or α-aryl ketones and lactone gave the corresponding “thermodynamic samarium enolates”. Enantioselective protonation of the samarium enolates with C2-symmetric chiral diols a

Samarium(II) diiodide-mediated reductive coupling of ketones with α,β-unsaturated esters is shown to afford enantioselectively γ-butyrolactones by the addition of 2,2′-bis(diphenylphosphinyl)-1,1′-binaphthyl (BINAPO) as a chiral ligand.
