Kennedy, Sean,Kethe, Anila,Qarah, Ahmad,Klumpp, Douglas A.
, p. 1932 - 1935 (2018)
A series of amido-acetals were reacted with the Br?nsted superacid, CF3SO3H, to provides indolizidine derives by a cyclization cascade. A mechanism is proposed involving formation of a vinylogous enol which undergoes a 6π-electrocycl

The scope of the diene-imine cyclocondensation reaction has been extended to the unstable Δ1-pyrroline.Cyclocondensation of this compound with the silylketene acetal derived from ethyl 2-p-anisyl-3-methylcrotonate provides the basis for a rapid
