Tetrahedron. 72:5465-5471
Stereoselective construction of all-carbon quaternary stereocenters by allylboration of chiral aldehydes is described. Sugar-derived aldehydes were allylated with geranylboronate or nerylboronate to provide γ-adducts possessing quaternary stereocent

Thin Solid Films. 518:993-1000
Carbon thin films are prepared from adamantane and dibromoadamantane by using a plasma-enhanced chemical vapor deposition method. Deposition rate for dibromoadamantane is approximately two times higher than that for pure adamantane. Infrared spectra

Thin Solid Films. 515:4111-4115
Amorphous fluorinated carbon films have been prepared by plasma enhanced chemical vapor deposition method using C 6 F 6 at substrate temperature of 400 °C. Thermal stability up to 400 °C is automatically achieved. Dielectric constant of the films i

The first total synthesis of (+)-vibsanin A, an 11-membered vibsane diterpenoid, was achieved, unambiguously establishing its relative and absolute stereochemistry. Highlights of the synthesis include the stereoselective formation of an all-carbon qu
