A Convenient Synthesis of Bipyrido-Fused Coumarins and Their Biological Evaluation

A convenient and efficient strategy has been devised for the synthesis of bipyrido-fused coumarins employing Kr?hnke's pyridine synthesis approach. In the present work, 4-hydroxycoumarins 1a–d were reacted with appropriate chalcones 2a–c to afford desired

Synthesis and antifungal activity of chalcone derivatives

In the present study, using chalcone as a lead compound, a series of its derivatives (compounds 1-30) were designed and synthesised. Their activity of anti-pathogenic fungi of plants has been evaluated. It is found that these compounds have good antifunga

An efficient synthesis of some new 3-bipyridinyl substituted coumarins as potent antimicrobial agents

As a part of the ongoing studies in developing new antimicrobials, a series of structurally novel 3-bipyridinyl substituted coumarin derivatives 4a-f and 5a-f were synthesized by a single-step reaction protocol under Krohnke's reaction conditions. 1

Synthesis and antimycobacterial activity of some N1-[1-[3-aryl-1- (pyridin-2-, 3-, or 4-yl)-3-oxo]propyl]-2-pyridinecarboxamidrazones

N1-[1-[3-aryl-1-(pyridin-2-,3-, and 4-yl)-3-oxo]propyl]-2- pyridinecarboxamidrazone derivatives were synthesized and tested for their in vitro antimycobacterial activity. Some compounds showed interesting activity against a strain of Mycobacter

NEUE WEGE ZU 1H-UND 2H-PYRROLEN

A synthesis of 1H-pyrroles is described starting with pyridine analogues of chalcones and involving the reacxtion of acetic anhydride with 1-pyrroline-1-oxides.Another route leads from 1-pyrrolines to 2H-pyrroles via bromination with N-bromosuccinimide and subsequent dehydrobromination in dimethylformamide.
