Enantioselective Spirocyclopropanation of para-Quinone Methides Using Ammonium Ylides
[Image: see text] The use of Cinchona alkaloid-based chiral ammonium ylides allows for the first highly enantioselective and broadly applicable spirocyclopropanation reactions of para-quinone methides. This strategy provides a straightforward protocol toward the chiral spiro[2.5]octa-4,7-dien-6-one...
