Abstract:
Cyanoacetamides are vital synthons in synthetic organic chemistry. However, methods to enantiopure cyanoacetamides have not yet been well explored. In this work, the preparation of cyanoacetamide synthons RS-(1a–4a) or methoxyacetamides RS-(1b–4b) in enantiopure/enriched form was investigated. Compounds S-1, S-2, R-1b, R-1a, andR-2b were prepared in enantiopure form (ee > 99%) while compounds S-4, R-2a, and R-4a were achieved in ee 9%, 80%, and 76%, respectively. Many baselines enantioselective HPLC separations of amines 1–4, their cyanoacetamides (1a–4a), and methoxyacetamides (1b–4b) were

Abstract:
The electron-ionization induced mass spectra of twenty six N-monosubstituted cyanoacetamides were recorded and their fragmentation patterns were studied. The effect of Nalkyl and N-aryl substituent to the fragmentation of the investigated compounds was discussed. Mechanistic generalization lead to a conclusion that fission of the carbon-carbon bonds next to carbonyl function or nitrogen were processes common for N-alkyl and N-(4-substituted phenyl) cyanoacetamides. In some amides, the elimination of acyl group by ketene fragment, gave rise to the more stable ion. Cycloalkyl amides could not fr

Abstract:
Fluorine plays a crucial role in modern pharmaceutical development owing to its distinct properties, such as high electronegativity and a compact atomic size. These features enable fluorine to improve a drug efficacy, selectivity, metabolic stability, and cell membrane permeability. To leverage these benefits, chromene-3-carboxamide derivatives (15a-e), incorporating a 2-fluorobenzene core, were synthesized by condensing salicylaldehydes (14a-d) or 1-hydroxy-2- naphthaldehyde (14e) with N-(2-fluorophenyl)acetamide (13) in a piperidine/ethanol mixture..
