Cyclopentathiadiazines, new heterocyclic materials from cyclic enaminonitriles.
نویسندگان
چکیده
Indene and cyclopentene enaminonitriles were reacted with SCl2, iBu3N and NCS to give the first cyclopenta[1,2,6]thiadiazines that showed unusual characteristics, one as a NIR dye and another as a liquid crystal.

Enaminonitriles in heterocyclic synthesis: a route to 1,3-diaryl-4-aminopyrazole derivatives.
Benzylcyanide and 4-nitrobenzylcyanide condensed with triethyl orthoformate and piperidine or morpholine to yield 2-aryl-2-piperidinyl or 2-morpholinylacrylonitriles. These coupled with aromatic diazonium salts to yield the 2-arylhydrazno-2-arylethane nitriles in good yields. The latter were converted into 4-aminopyrazoles in good yields using the Thorpe-Ziegler cyclization.
متن کاملEfficient Synthesis of 5,5-Disubstituted Bis-hydantoins/spirohydantoins and a Tetrakis-analogue: A Drug-like Multi-cyclic Scaffold
An easy method was developed for the efficient preparation of diversely new 5,5-disubstituted N(3),N'(3)-linkaged bis-hydantoins. At first, using the same methods, some ketones and terephthalaldehyde were converted to several hydantoins and a new bis-hydantoin , respectively. Then 1,6-dibromohexane, as a mild reagent, was employed for the alkylation and incorporation of synthesized substrates t...
متن کاملImportance of Heterocyclic Chemistry: a Review
Heterocyclic compounds are of very much interest in our daily life. Heterocyclic compounds have one or more hetero atoms in their structure. They may be cyclic or non cyclic in nature. Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxid...

متن کاملAcyclic to cyclic aminophosphonic and phosphinic acids
The results presented in this account deal with the synthesis of acyclic αor β-aminophosphonates or phosphinates and with the synthesis of heterocyclic compounds, where the phosphorus and/or the nitrogen atoms can be embedded in the heterocyclic core, showing new perspectives in bioactive molecules.
