## Abstract A series of Biginelli compounds was synthesized using TsOH as a catalyst under microwave irradiation. This simple method provided the title compounds in 86%β98% yields by the reaction of aromatic aldehydes with 1,3βcarbonyl compound and urea. The structure of 4o was determined by single
New One-Pot Method for the Synthesis of Alkynyl Sulfonate Esters Using Ultrasound. -Alkynyl sulfonates esters (III) are directly obtained by the coupling of terminal alkynes with hypervalent iodo compounds in the presence of AgOTf. Ultrasonic irradiation results in a remarkable increase in reactivit
