An efficient synthesis of symmetrical N,N′-alkylidene bisamides
catalyzed by phosphortungstic acid |
Symmetrical
N,N′-alkylidene bisamides have
been synthesized by condensation of aromatic aldehydes and amides in the
presence of phosphotungstic acid as a catalyst under thermal and neat
microwave irradiation conditions. |

Synthesis, configurational analysis and antimicrobial
activity of imidazolidinone, thiazolidinone and isoxazolone derivatives of 9,10-phenanthrenequinone |
A facile
synthesis of imidazolidinone, thiazolidinone and isoxazolone derivatives has
been described by Knoevenagel type condensation reactions of
9,10-phenanthrenequinone with active methylene heterocycles/compounds. The
products have been characterized by spectral data. Semiempirical studies have
been performed to understand the stereochemical course of the reaction. Some
of the synthesized products have been screened for antimicrobial activity. |

Conventional as well as microwave assisted synthesis
and antimicrobial screening of 4-aryl-3-chloro-1-[(5-nitroindazol-1-yl)
acetamido]-2-oxo-azetidines |
Several new
4-aryl-3-chloro-1-[(5-nitroindazol-1-yl) acetamido]-2-oxo-azetidines, 4a-l have been synthesized from
2-(5-nitroindazol-1-yl) acetamidyl amino arylidenes, 3a-l. The reactions have been
carried out by both conventional as well as microwave method. All the
synthesized compounds have been screened for their antibacterial and
antifungal activity against some selected micro organisms. |

Synthesis of 4-(3H)-quinazolinones by
microwave assisted tandem reaction and evaluation of their antibacterial and
antifungal activities |
A one pot synthesis of quinazolinone derivatives
from the reaction of anthranilic acid and primary aromatic amines with Vilsmeier
reagent (DMF/POCl3) has been carried out under microwave
irradiation. All the synthesized compounds have been screened for their in
vitro antibacterial and antifungal activity. |
