alpha-Ester-substituted 1,3-dienylphosphonates 7 and 8, prepared by the Knoevenagel condensation, underwent intramolecular [2 + 2] cycloaddition in the presence of Lewis acid to form bicyclo[4.2.0] (26-57% yield) and bicyclo[3.2.0]skeleton (14-38% yield), respectively. Similar treatment of homologous 1,3-dienylphosphonate 11 and...

Utsunomiya T, Doki Y, Takemoto H, Shiozaki H, Yano M, Inoue M, Yasuda T, Fujiwara Y, Monden M.
PMID: 11984736
Gastric Cancer. 2000 Dec;3(4):193-201. doi: 10.1007/pl00011717.

BACKGROUND: Beta-catenin plays two distinct roles, in intercellular adhesion by E-cadherin, and in transcriptional activation via TCF/LEF. Theoretically, the former role is tumor-suppressive, while the latter is oncogenic. We investigated the involvement of beta-catenin in the histogenesis and clinical...

1,2,4-Triphenylbenzene and 2,2'-methylenedioxy-1,1'-binaphthalene successfully photosensitized the aminations of 1,2-benzo-1,3-cycloalkadienes, arylcyclopropanes, and quadricyclane with ammonia and primary amines in the presence of m- or p-dicyanobenzene, which gave the 4-amino-1,2-benzocycloalkenes, 3-amino-1-arylpropanes, and 7-amino-5-(p-cyanophenyl)bicyclo[2.2.1]hept-2-ene, respectively. A key pathway for the photosensitized amination...
