A new class of spiro pyrrolidines, dispiro [oxindole-cyclohexanone] pyrrolidines, 1 dispiro
[oxindole-tetrahydronaphthalen-1-one] pyrrolidines, 2 dispiro [oxindole-arylidene …

Antibiotic resistance is a global public health threat. There has been considerable interest in
the development of novel compounds with antimicrobial, anti-mycobacterial, and antiviral …

Synthesis of a series of novel spiro pyrrolidines has been accomplished by 1, 3-dipolar
cycloaddition reaction of azomethine ylide generated from phenylalanine and isatin with …

This is the first book devoted entirely to the chemistry of the six naphthyridine systems.
Because of structural uncertainties and confusing nomenclature, much of the early literature …

A volume in the Chemistry of Heterocyclic Compounds series, this book provides a summary
of the chemistry of each of the six naphthyridine systems along with tables of known simple …

Refluxing dimethyl acetylenedicarboxylate (DMAD) or 1, 2-dibenzoylacetylene with isatin-3-
thiosemicarbazone or isatin-3-thiocarbohydrazone in methanol produced 3-substituted …

Twenty derivatives of isatin (1H-indole-2, 3-Dione) were synthesized by the schematic route
as per as scheme. These were further characterized by spectroscopic analysis. All the novel …

Abstract The 1, 3-dipolar cycloaddition reactions with trans azomethine ylide produce
spirooxindole derivatives, which are active against certain bacterial pathogens …

The N—C and C—C bond distances in the pyrrolizidine moiety of the title compound,
C33H26N2O4, are slightly longer than the normal values. This is due to the steric forces …
