Diketene (C(4)H(4)O(2)) monomers were isolated in cryogenic Ar (15 K) and Xe (30 K) matrices. The infrared (IR) spectra of the freshly deposited matrices show that diketene monomers exclusively adopt the 4-methylene-oxetan-2-one form. In situ photochemical transformations of diketene were

A convenient synthetic protocol was elaborated for creation of combinatorial libraries of 1-(R(1)-phenyl)-5-methyl-N-R(2)-1H-1,2,3-triazole-4-carboxamides. As starting materials, commercially available or readily prepared azides, amines, and diketene were selected for the reaction which has proceeded in a one-pot system with high yields

In this work, 1,2,3,4,5,8-hexahydro-1,3,7-trimethyl-2,4-dioxopyrido[2,3-d]pyrimidine-6-carboxamide derivatives were synthesized in a simple and efficient method from the four-component condensation reaction of diketene, an aliphatic or aromatic amine, an aromatic aldehyde, and 6-amino-1,3-dimethyluracil in the presence of a catalytic amount of p-toluenesulfonic acid

Two acetoacetylated derivatives of Mycobacterium leprae with variable hapten groups and a conjugate with tetanus toxoid were prepared. These were tested as antigens along with unmodified M. leprae in the leucocyte migration inhibition response of leucocytes from clinically, bacteriologically and
