The Heterocyclic and Synthesis Group's flagship biennial meeting in the Lake District village of Grasmere, Cumbria.Plenary lectures and supporting talks, plus short talks from postgraduates and postdo...
The art of chemical synthesis is driven to a great extent by synthetic chemists seeking to find more efficient routes to heterocyclic compounds; molecules at the core of pharmaceutical agents, bioacti...
We are pleased to invite you to attend the Symposium on Advances in Heterocyclic Organic Chemistry which will be held on the 1st and 2nd of September 2016 in Sheffield, United Kingdom.
The 2016 symposium will be held on 20th September at Sygnature Discovery, BioCity, Nottingham.
A new series of 1,3,4,5-tetrasubstituted pyrazoles have been synthesized by the 1,3-dipolar cycloaddition of suitable nitrilimines to 3-propylidene and 3-benzylidene-phthalide. Both analytical and spe...
Novel 1,3-dialkylimidazolinium and 1,3- dialkyltetrahydropyrimidinium hexafluorophosphate salts as N-heterocyclic carbene precursors were prepared by reacting N,N'-dialkylethandiamine or N,N'-dialkylp...
Some new 4-oxo-4H-chromone derivatives bearing nitrogen heterocyclic systems were achieved by treatment of 3-[(4-aminophenylimino) methyl]-6-chloro-4-oxo-4H-chromene (2) with some aldehydes, cyclic ox...
This review presents a systematic and comprehensive survey of the methods of preparation and the chemical reactivity of cyanoacetamide derivatives. These compounds are important intermediates for the ...
A new class of spiro-triazoles (4a-m) were synthesized from the reaction of corresponding nitrilimines 2 with substituted heterocyclic benzoylhydrazones 3 in good yields. The spectral data of the new ...
