β-Oxoanilides in heterocyclic synthesis : Synthesis of Some New Pyrimidine containing Sulphonamido moiety Derivatives
Butanamide derivative (1) coupls smoothly with arenediazonium salts to afford the hydrazone (3). The latter product reacts with dimethylformamide – dimethylacetal (DMF-DMA) and or malononitrile to afford the substituted 1,4dihydropyridazines (5,6). Several new pyran (8), thiophene (9), pyrazole (14) and isothiocyanate derivatives (17,18) have been synthesized by the reactions of butanamide with...
متن کاملCatalytic dynamic kinetic resolutions with N-heterocyclic carbenes: asymmetric synthesis of highly substituted β-lactones.
New DKR type: An N-heterocyclic carbene (NHC)-catalyzed dynamic kinetic resolution of racemic α-substituted β-keto esters has been developed. This method relies on the epimerization of an NHC-enol intermediate before subsequent aldol/acylation events. Highly substituted β-lactones are produced in good yield with good to excellent selectivities (see scheme).
متن کاملN(2)-substituted D,L-cycloserine derivatives: synthesis and evaluation as alanine racemase inhibitors.
A select series of N(2)-substituted D,L-cycloserine derivatives were prepared a ndevaluated for inhibitory activity against purified alanine racemases (alr gene product) from Escherichia coli, Staphylococcus aureus, and Mycobacterium tuberculosis, as well as in a growth inhibition assay. N(2)-Modification led to loss of enzymatic inhibitory activity in most cases consistent with a recent propos...
متن کاملNovel C-2 substituted carbapenem derivatives. Part I. Synthesis and biological activity of non-aromatic heterocyclic derivatives.
A new series of carbapenems, having a saturated or partially unsaturated heterocycle at C-2, has been synthesised. The in vitro antibacterial activity of these compounds and their stability to human dehydropeptidase-1 (DHP-1) are described. The stereochemistry of the C-2 side-chain and the presence of a double bond in the heterocycle were shown to have significant effects on the stabilities of ...
متن کاملSynthesis of tetra-substituted phenanthroimidazole derivatives using SBA-Pr-SO3H
A one pot four-component reaction of 9,10-phenanthraquinone, aromatic aldehyde, aniline, and ammonium acetate was designed for the preparation of tetrasubstituted imidazoles (phenanthro[9,10-d]imidazole) derivatives in the presence of SBA-Pr-SO3H as a mesoporous solid acid catalyst. Phenanthro[9,10-d]imidazole derivatives were produced by the use of this technique in short reaction times and go...
