DOI: 10.1039/c8cc07567k
Abstract: The catalytic asymmetric ene-type reactions of vinylogous hydrazone were accomplished by using chiral N,N'-dioxide-metal salt complexes as catalysts. A wide range of electrophiles, including isatins, α-ketoester, imines, and aldehydes reacted with (E)-2-methyl-N-(piperidin-1-yl)prop-2-en-1-imine efficiently, affording the… read more here.
