New Advances in Chemical Research, May 2021.Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 256-96-2, Name is 5H-Dibenzo[b,f]azepine, molecular formula is C14H11N, belongs to pyrrolines compound, is a common compound. In a patnet, author is Okano, T, once mentioned the new application about 256-96-2, Category: pyrrolines.
Addition-elimination reaction of highly electrophilic difluoroolefin, 5-difluoromethylene-3-pyrrolin-2-ones
1-Alkyl-5-difluoromethylene-3-pyrroline-2-ones 2 were generated from 1-alklyl-5-trifluoromethyl-3-pyrrolin-2-ones 1 via dehydrofluorination with methyllithium at -78 degrees C. Spontaneous addition-elimination reaction of 2 with enolate anion of 1 gave fluorinated pyrrolinonylmethylidenepyrrolinones 3.
