Nawrocka, Wanda,Sztuba, Barbara,Opolski, Adam,Wietrzyk, Joanna,Kowalska, Maria W.,Glowiak, Tadeusz
, p. 3 - 10 (2001)
The reaction of 2,2,4-trimethyl-1H-2,3-dihydro-1,5-benzodiazepine (1) with cinnamoyl chloride leading to the formation of 1-cinnamoyl derivative 2 is described. Two novel benzodiazepines, 2,2,4-trimethyl-1H-2,3,4,5-tetrahydro-1,5-benzodiazepine (3) and 1-
New synthesis of diazepino[3,2,1-ij]quinoline and pyrido[1,2,3-de] quinoxalines via addition-elimination followed by cycloacylation

Starting from mononitrotetrakis(iodophenyl)methane as monomer, we report the preparation of the first pre-functionalised porous aromatic frameworks (PAFs) and their application as supports for organometallic catalysts. Neutral coordinate imino-pyridine Schiff base (PAF-NPy) or chiral bis-amino (PAF-NPro) ligands were obtained by post-synthetic treatment of PAF-NH2 and treated with copper(I) or rhodium(I) to yield the corresponding supported transition-metal catalysts. The as-prepared PAF-NN-M catalysts exhibited activity and selectivity similar to that of the corresponding homogeneous catalysts and were easily removed from reaction media and recycled without loss of activity or selectivity. New copper catalysts: The preparation of pre-functionalised porous aromatic frameworks (PAFs) and their application as supports for organometallic catalysts (see figure) is reported for the first time.
Stereochemistry of N-acyltetrahydro-1,5-benzodiazepines using NMR spectra, X-ray crystallography and semiempirical MO calculations

, p. 2059 - 2070 (2007/10/03)
The preferred conformations of N-acyl derivatives of 2,2,4-trimethyl-1H- tetrahydro-1,5-benzodiazepines 6-9 have been studied using NMR spectral techniques. In the case of N1,N5-diformyl derivative 9, there is an equilibrium between
STEREOSELECTIVE BRIDGING OF TETRAHYDRO-1,5-BENZODIAZEPINES
Kalyanam, Nagabushanam,Manjunatha, Sulur G.
, p. 1131 - 1136 (2007/10/02)
A reaction of tetrahydro-1,5-benzodiazepines with aromatic aldehydes which yields the hitherto unknown 1,5-methanotetrahydro-1,5-benzodiazepines as a single stereoisomer is described.The stereochemistry of the products is established using proton nmr spec
NEW SYNTHESIS OF DIHYDRO- AND TETRAHYDRO-1,5-BENZODIAZEPINES BY REDUCTIVE CONDENSATION OF O-PHENYLENEDIAMINE AND KETONES IN THE PRESENCE OF SODIUM BOROHYDRIDE
Morales, Hilda R.,Bulbarela, Arturo,Contreras, Rosalinda
, p. 135 - 139 (2007/10/02)
Dihydro- and tetrahydro-benzodiazepines have been synthesized from o-phenylenediamine dihydrochloride and aliphatic ketones in the presence od sodium borohydride.
