The three-component condensation of pyridinium acylmethylides generated in situ with aromatic aldehydes and 4-hydroxy-6-methylpyridones gave a series of 2-acyl-3-aryl-3,5-dihydrofuro[3,2-c]pyridin-4(2H)-ones. The reaction proceeds diastereoselectivel

This paper considers a combined scheme of insertion of a satellite into a geostationary orbit with the help of high and low torque thrusters. The start orbit is high elliptical and is formed by the third stage of the launch vehicle. Further insertion
