The title compound, C(15)H(15)NO, crystallizes with two mol-ecules in the asymmetric unit. The H-N-C=O units are in a trans conformation, similar to that observed in N-(3,4-dimethyl-phen-yl)benzamide, N-(2,6-dichloro-phen-yl)benz-amide and other benzanilides. The central -NHCO- bridging unit is tilted at angles of 17.1 (3) and 16.4 (3)° to the benzoyl ring in the two mol-ecules. The two rings (...

The conformations of the N-H and C=O bonds in the structure of the title compound (N26DMP4CBA), C(15)H(14)ClNO, are anti to each other, similar to that observed in N-phenyl-benzamide, N-(3,4-dimethyl-phen-yl)benzamide, N-(2,6-dichloro-phen-yl)benzamide and other benzanilides. There are three mol-ecules in the asymmetric unit of N26DMP4CBA. The central amide group is tilted with respect to the b...

The core of teleocidin B4, a complex fragment of a natural product containing two quaternary stereocenters and a penta-substituted benzene ring, was synthesized in four C-C bond-forming steps starting from tert-butyl derivative 1. The first step involved alkenylation of the tert-butyl group with a vinyl boronic acid, followed by the successful annulation of the cyclohexane ring to the benzene n...

This study deals with a new and efficient metal-free regioselective synthesis of pyrimido-fused indazoles with nitrogen ring junction motifs. We have developed a metal-free domino type reaction between 3-aminoindazole, aryl aldehydes and aceotophenones in the presence of KOH/DMF that leads to pyrimido[1,2-b]indazole analogues. Response Surface Methodology (RSM) coupled with a Box-Behnken design...

1. N-Hydroxylation of aniline and 4-chloroaniline was quantified in rainbow trout microsomal preparations using h.p.l.c.-liquid scintillation methods. Radioactive phenylhydroxylamine and 4-chlorophenylhydroxylamine metabolites were identified by co-elution with non-labelled standards. The method provided resolution of metabolite standards, and quantification of both N-hydroxylated metabolites w...
