11-(4-Meth­oxy­phen­yl)-3,3-dimethyl-2,3,4,5,10,11-hexa­hydro-1H-dibenzo[b,e][1,4]diazepin-1-one monohydrate

In the title compound, C22H24N2O2·H2O, the co-crystallized water mol­ecule inter­acts with the N and O atoms of the mol­ecule through Ow—H⋯N, Ow—H⋯O(meth­yl) and N—H⋯Ow hydrogen-bonding inter­actions. These hydrogen bonds, along with the inter­molecular N—H⋯O=C hydrogen-bonding inter­actions, connect the mol­ecules into a three-dimensional network. The dihedral angle between the two aromatic rings is 65.46 (10)°

Synthesis and Some Reactions of 3-Chloro-2-(cyanomethylene)-1,2-dihydroquinoxalines

2,3-Dichloroquinoxaline and some of its derivatives have been reacted with malononitrile and ethyl cyanoacetate to yield a variety of 3-chloro-2-(cyanomethylene)- 1,2-dihydroquinoxaline derivatives. The reaction of 3-chloro-2-(dicyanomethylene)-1,2- dihydroquinoxaline (2e) with pyridine and its methyl derivatives led to the zwitterionic structures 6a-6c. The structures of the newly synthesized compounds were assigned by spectroscopic data and elemental analyses

Synthesis of 2-Chloro-3-(2-naphthyloxy)quinoxaline

A mixture of 2,3-dichloroquinoxaline 1 [1] (1.0 g, 5 mmol) and 2-naphthol (0.72 g, 5 mmol) in pyridine (10 mL) was heated to 130°C for 3 h, with magnetic stirring, to give a dark-brown reaction mixture.[...

Comparative study of microwave assisted and conventional synthesis of novel 2-quinoxalinone3- hydrazone derivatives and its spectroscopic properties

A series of novel quinoxalin-2(1H)-one-3-hydrazone derivatives, 2a -8d were synthesized via condensation of 3-hydrazinoquinoxalin-2(1H)-one, 1, with the corresponding ketones under microwave irradiation. The microwave assisted reaction was remarkably successful and gave hydrazones in higher yield at less reaction time compared to conventional heating method. The chemical structures of the compounds prepared were confirmed by analytical and spectral data
