Herein, we present a novel one-pot aqueous reaction for the synthesis of 2-iminothiazolines and 2-aminothiazoles using isocyanides, amines, sulfur, 2′-bromoacetophenones. The three-component preparation thioureas is followed by cyclization leading to heterocyclic product. This efficient mild procedure features excellent step- atom-economy enables chromatography-free diversely substituted 2-imin...

The reactions of human hemoglobin with a series of 13 alkyl isocyanides have been examined in equilibrium titration experiments at pH 7, 20 degrees C. The ligands include: methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, (+)- and (-)-sec-butyl, tert-butyl, n-pentyl, n-hexyl, cyclohexyl, and benzyl isocyanides. All of these compounds exhibit sigmoidal binding curves; however, the amount of...

Isocyanide-based multicomponent reactions (IMCR) are by far the most versatile reactions that can construct relatively complex molecules by one-pot synthesis. More importantly, the development of post IMCR modifications significantly improves the scaffold's diversity. Here, we describe the use of N-Boc protected hydrazine together with α-amino acid derived isocyanides in the Ugi tetrazole react...
