Molecules that serve as versatile branch points for the synthesis of pharmaceutically or biologically active products, besides being of interest in their own right, are especially valuable targets for asymmetric catalysis. The 1,4-benzoxazinone and 1,4-benzoxazine systems are intriguing because they are present in clinically significant pharmaceuticals and other biologically active molecules. O...

The blood findings in five monkeys after experimental high intestinal obstruction are reported. All animals showed the marked rise in non-protein nitrogen characteristic of intestinal obstruction in man and the dog. Two monkeys showed a very marked drop in chlorides, the others a less marked fall. Coincident with the change in chlorides there is a rise in the CO(2)-combining power. The uric aci...

educational researchers have provided evidence that teachers’ emotional intelligence has strong effects on various aspects of teaching and learning. yet, in the field of teaching english to speakers of other languages (tesol), inquiry into teachers’ emotional intelligence is nearly limited. given its documented powerful impact on teaching practices and student learning, it is critical to pursue...

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...

Palladium-catalyzed direct cross-coupling of aryl chlorides with a wide range of (hetero)aryl lithium compounds is reported. The use of Pd-PEPPSI-IPent or Pd2(dba)3/XPhos as the catalyst allows for the preparation of biaryl and heterobiaryl compounds in high yields under mild conditions (room temperature to 40 °C) with short reaction times.
