Chemical Research Letters, May 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 256-96-2, Name is 5H-Dibenzo[b,f]azepine, SMILES is C12=CC=CC=C1C=CC3=CC=CC=C3N2, in an article , author is Naitoh, R, once mentioned of 256-96-2, HPLC of Formula: https://www.ambeed.com/products/256-96-2.html.
Formation of 3-pyrrolin-2-ones via 5-endo-trig cyclization
Anionic cyclization of N-benzyl-3-phenylsulfanyl-2-propenamide derivatives gave the corresponding 3-pyrrolin-2-ones. Mechanistic investigation using deuterated starting materials revealed this cyclization proceeds via a 5-endo-trig process.
