Kamala Das with utmost frankness writes about a number of themes in her poetry. One of them is the man-woman relationship. In her poetry, her personal experiences turn into universal through her fervent expression. In fact, Das in her poems seeks for love, especially mutual love with emotional bond, and tries to achieve consummation in love. The male dominated family relation with her husband gives her no space to articulate her passionate longing for love. So, she chooses to bare her longings in her writing through which she is in quest for liberating her 'caged self ". [ABSTRACT FROM AUTHOR]

A short, proficient, and regioselective synthesis of biheterocyclic 5,6-dihydro-quinazolino[4,3- b ]quinazolin-8-ones has been revealed via an Fe(0)-powder-mediated, one-pot reductive cyclization protocol. Mechanistic investigation proved that water acts as a source of hydrogen for the reduction of the nitro group and the reaction rate was accelerated by an aldehyde. The designed transformation works under aerobic conditions, providing a series of bio-inspired molecular scaffolds. In addition, the photophysical study showed blue fluorescence emission with a good fluorescence quantum yield.

An efficient and atom-economical palladium-catalyzed intramolecular cross dehydrogenative coupling (CDC) reaction has been developed for the construction of highly π-conjugated benzimidazo[1,2- a ]quinoline-fused isoxazole scaffolds using molecular oxygen as sole oxidant. The approach portrayed wide substrate scope with good functional group tolerance and depicted a useful tool for the generation of fluorescence active compounds with high quantum yield. Synthetic versatility of the method via Fe-catalyzed reductive isoxazole ring cleavage toward pyridine, pyrimidine, pyrazole fused heteropolycyclic compounds has been showcase.
