Trifluoroethanol as an efficient reaction media for the synthesis of pyran skeleton through domino Knoevenagel-hetero-Diels-Alder reaction with non-activated alkynes

Trifluoroethanol as an efficient media for the domino Knoevenagel-hetero-Diels-Alder reaction of O-propargyloxy benzaldehydes as non-activated terminal alkynes with some active methylene compounds has been described. Short reaction time, easy work-up, good to high yields, and mild reaction conditions are advantages of this new media. Graphical Abstract: [Figure not available: see fulltext.]

Copper(I) iodide catalyzed domino Knoevenagel hetero-Diels-Alder reaction of terminal acetylenes: Synthesis of pyrano[2,3-c]pyrazoles

A new and efficient CuI-catalyzed domino Knoevenagel hetero-Diels-Alder reaction of 1-oxa-1,3-butadienes with terminal unactivated acetylenes as building blocks to afford pyrano[2,3-c]pyrazoles has been developed. The products were obtained in good to hig
