Synthesis of dihydropyrano[2,3-c]pyrazole scaffolds by methylene blue (MB+) as a photo-redox catalyst via a single-electron transfer (SET)/energy transfer (EnT) pathway

Synthesis of dihydropyrano[2,3-c]pyrazole scaffolds by methylene blue (MB+) as a photo-redox catalyst via a single-electron transfer (SET)/energy transfer (EnT) pathway

A new environmentally friendly plan was created to make dihydropyrano [2,3-c]pyrazole structures without using metals. This plan involves combining ethyl acetoacetate, hydrazine hydrate, aldehyde derivatives, and malononitrile in a radical tandem Knoevenagel-Michael cyclocondensation reaction. We us...
