PIFA-mediated intramolecular -arylation of 2-aminoquinoxalines to afford indolo[2,3-]quinoxaline derivatives.

We present the PIFA-mediated intramolecular -arylation of 2-aminoquinoxalines at room temperature for the first time. This method provides a wide range of indolo[2,3-]quinoxalines in good to excellent yields within a short time. The C-H bond functionalization occurs without the need for an inert atmosphere or additives.

Comparative Agronomic Performance and Reaction to Fusarium wilt of × and × derivatives.

The development of transgressive phenotype in the segregating populations has been speculated to contribute to niche divergence of hybrid lineages, which occurs most frequently at larger genetic distances. Wild species are considered to be more resistant against major biotic and abiotic stresses than that of the cultivated species. In the present study, we assessed the comparative agronomic performance of lentil ( subsp.

A rare variant angioarchitecture of upper abdomen.

Vascular anomalies are frequently encountered in abdomen. But they are usually asymptomatic and diagnosed accidently during angiography or surgery leading into severe complications. Thus knowledge of angioarchitecture in abdomen, whether normal or variant, is considered prerequisite for successful, uncomplicated surgeries and interventional radiology.
