THE TITLE COMPOUND [SYSTEMATIC NAME: 1(2)-amino-4(2)-(1-naphth-yl)-1,4(1,4)-dibenzenacyclo-hexa-phane], C(26)H(23)N, was synthesized from 4-amino-13-bromo-[2,2]paracyclo-phane and 1-naphthalene-boronic acid in the presence of 1,4-dioxane. It is a new cyclo-phane-derived compound which can be regarded as a prospective ligand for asymmetric synthesis and catalysis. The benzene rings of the paracy...

We determined age-related reference values for urinary free amino acids (in mmol/mol creatinine) in first morning urine specimens from 360 control subjects who were divided into nine age groups: birth to 1 month, 1-6 months, 6-12 months, 1-2 years, 2-4 years, 4-7 years, 7-10 years, 10-13 years, and older than 13 years. Except for taurine and 3-methylhistidine, the concentration of all the amino...

The question of the significance of free amino acids in soil or other cultural media has received attention in recent years in the fields of plant physiology (1, 3, 7, 13, 14, 15, 16, 17), soil microbiology (4, 5, 11, 16) and soil chemistry (9, 10,12). Although it originally appeared that free amino acids were not to be found in soils, later reports (2, 10) indicated they could be extracted wit...

A new series of 2-[2-(2,6-dichlorophenyl)amino]phenyl methyl -3-[(1-phenyl-5-substituted phenyl)-5-hydro-1H-pyrazol-3-yl-amino]-6,8-dibromoquinazolin-4(3H)-ones C1-13 have been synthesized by the reaction of 2-[2-(2,6-dichlorophenyl)amino]phenylmethyl-3-substituted phenyl chromene amido-6,8-dibromo-quinazolin-4(3H)-ones with phenylhydrazine in the presence of glacial acetic acid. The chalcones ...
