Copper perchlorate is found to be a heterogeneous catalyst for an efficient and greener synthesis of 4-substituted 2H-chromen-2-ones via von Pechmann condensation of substituted phenols and beta-keto esters in solventless media with excellent yields using ultrasound irradiation. The present methodology offers several advantages such as excellent yields,(More)
Autopsy safety was not much of a consideration until the 1980s when HIV infection appeared. At first, the emphasis was placed on the prevention of infection by establishing "universal precautions". Along with this came procedures and regulations to minimize the possibility of cuts and needle sticks. Other hazards were eventually identified, and appropriate(More)
Copper perchlorate hexahydrate as an efficient catalyst was used for the synthesis of polyhydroquinolines by four-component condensation reaction of aldehyde, ethyl acetoacetate, dimedone, and ammonium acetate in excellent yields and short reaction times at room temperature under ultrasound irradiation. This novel synthetic method is especially favoured(More)

Diverse instruments have been used to encourage developing agriculture. In the process, billions of dollars have been spent on providing incentives to peasants. Given scarce resources, an important concern has been the issue of what policy instruments to emphasize. In this regard, useful policy information can be gleaned from the role of expected profits(More)
Substituted dihydropyridine calcium channel blockers are used in the treatment of cardiovascular diseases. Dihydropyridines are considered as analogue of dihydropyrimidines. In present study newly synthesized test compound 5-Acyl-6-methyl-4(2’,3’methylenedioxy) phenyl 2 S ethyl 1, 4-dihydropyrimidine, a dihydropyrimidine derivative was investigated with an(More)
