A class of carbonic anhydrase I – selective activators

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
A series of ureido and bis-ureido derivatives were prepared by reacting histamine with alkyl/aryl-isocyanates or di-isocyanates. The obtained derivatives were assayed as activators of the enzyme carbonic anhydrase (CA, EC 4.2.1.1), due to the fact that ...

Improvement Upon a Largely Forgotten Method for the Synthesis of N-Alkyl Urazoles

Reactions
N-Alkyl urazoles are important heterocyclic compounds that serve as important precursors to potent N-alkyl 1,2,4-triazoline-3,5-dione electrophiles. Traditional methods for urazole synthesis rely upon the use of toxic isocyanates.

Homochiral Acyl Isocyanates as Diagnostic NMR Probes for the Enantiomeric Purity of Chiral Alcohols

Sultan Qaboos University Journal for Science, 2000
The first reported acyl and sulfonylisocyanates were developed and tested in reactions with chiral alcohols to afford diastereomeric carbamates. NMR analysis of these investigates the chemical shift discrimination that would allow these activated ...
