title = "Catalyst Choice for Highly Enantioselective [3 + 3]-Cycloaddition of Enoldiazocarbonyl Compounds",
abstract = "Chiral copper(I) catalysts are preferred over chiral dirhodium(II) catalysts for [3 + 3]-cycloaddition reactions of enoldiazocarbonyl compounds with nitrones and acyliminopyridinium ylides, forming chiral oxazines and pyrazines in very high yield and enantioselectivity. Yields and stereoselectivities from reactions of enoldiazoketones are virtually the same as those from the corresponding esters and amides, but products from enoldiazoketones are precursors to chiral 1,3-dicarbonyl derivatives that provide additional opportunities in heterocyclic synthesis through the formation of pyrazoles and isoxazoles.",
