different acid chlorides (2a-d) reacted with anthranilic acid to produce 2-substituted-3, 1-benzoxazin-4-one (3a-d) which was used as starting material to synthesize some condensed and non-condensed heterocyclic compounds by reaction with nitrogen nucleophiles e.g., hydrazine hydrate, and formamide. some of the newly synthesized analogues were chosen to evaluate their cytotoxic activity against...
Aqueous phase recirculation increased the bio-crude yield and energy recovery along with promoting production of N-heterocyclic compounds that lead to harsher required hydrotreating conditions.
N-heterocycles, both saturated and unsaturated, are ubiquitous biologically active molecules that extremely appealing scaffolds in drug discovery programs. Although classical synthetic methods have been developed to access many relevant N-heterocyclic scaffolds, representing well-established reliable routes, some do not meet the needs of sustainability. In this context, several advances made to...
We report the synthesis of nine new N-heterocyclic carbene gold bifluoride complexes starting from the corresponding N-heterocyclic carbene gold hydroxides. A new methodology to access N,N'-bis(2,6-diisopropylphenyl)imidazol-2-ylidene gold(I) fluoride starting from N,N'-bis(2,6-diisopropylphenyl)imidazol-2-ylidene gold(I) hydroxide and readily available potassium bifluoride is also reported. Th...
