ChemInform Abstract: A Practical Synthesis of Novel Rho-Kinase Inhibitor, (S)-4-Fluoro-5-(2-methyl-1,4-diazepan-1-ylsulfonyl)isoquinoline
Autor: Jyunji Katsuyama, Tadaaki Ohgiya, Hitoshi Sakai, Kimiyuki Shibuya, Masayuki Masumoto, Noriaki Gomi
Publikováno v: ChemInform. 42
The synthesis of the novel inhibitor (VII) is achieved in multi-kilogram scale overcoming two major issues: the need of developing a regioselective chlorosulfonylation reaction at C-5 of fluoroisoquinoline and the stereochemical purity in the asymmet

Synthesis and Properties of the Tridecafulvene Derivatives. The Substituent Effect at the 14-Position on the Tropicity of Thirteen-Membered Fulvene System
Autor: Jyunji Katsuyama, Juro Ojima, Keiko Kitamura, Masayuki Masumoto, Masahiko Iyoda
Publikováno v: Bulletin of the Chemical Society of Japan. 62:1188-1192
Dimethylbisdehydrotridecafulvene derivatives bearing various substituents at the exocyclic bond have been synthesized and the inductive effect of substituents upon the tropicity of the thirteen-membered ring is discussed on the basis of the spectral

Publikováno v: Journal of the Chemical Society. Chemical communications. 1987(8):534-536
The title annulenes have been synthesized and their 1H n.m.r. spectra indicate that the [28]- and [34]-annulenes as well as the lower-membered ones can sustain a ring current.

The Synthesis of 12-Ethoxy-4,9-methanoaza[12]annulene, a 12π-Electron Vinylogue of Pyridine
Autor: J\={u}ro Ojima, Masayuki Masumoto, Shigeyasu Kuroda, Shuji Hirooka, Yoshihiko Nozawa
Publikováno v: Bulletin of the Chemical Society of Japan. 60:3803-3804
The title aza[12]annulene has been synthesized by Beckmann rearrangement of the oxime from the methano[11]annulenone, followed by alkylation of the resulting lactam. Examination of the 1H NMR spectrum indicates that the aza[12]annulene is slightly pa
