Engineering of a promiscuous 4-oxalocrotonate tautomerase (4-OT) resulted in an unusual cofactor-independent cyclopropanationenzyme that promotes the stereoselective addition of diethyl 2-chloromalonate to substituted cinnamaldehydes to afford various cyclopropanes with high diastereo- and enantiopurity.
