Enamine-Iminium Ion Nazarov Cyclization of α-Ketoenones
摘要:
The mono-triflate salts of some chiral nonracemic 1,2-diamines react with alpha-ketoenones in a stoichiometric reaction to form products of the Nazarov cyclization in high enantiomeric ratios. The mechanism appears to involve rearrangement of an enamine-iminium ion.
