Asymmetric Bronsted acid-catalyzed Nazarov cyclization of acyclic α-alkoxy dienones

A Bronsted acid-catalyzed asymmetric Nazarov cyclization of acyclic α-alkoxy dienones has been developed. The reaction offers access to chiral cyclopentenones in a highly enantioselective manner. The reaction is complementary to our previously reported Bronsted acid-catalyzed electrocyclization reactions, which provided differently substituted optically active cyclopentenones with a fused tetrahydropyrane ring in good yields and with excellent enantioselectivities. I've got 5 on it! An enantioselective Bronsted acid-catalyzed Nazarov cyclization of acyclic α-alkoxy dienones that affords optically active cyclopentenones in good yields and excellent enantiomeric excess has been developed.

Enamine-lminium ion nazarov cyclization of α-ketoenones

[Chemical equaction presented] The mono-triflate salts of some chiral nonracemic 1,2-diamines react with α-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.
