A practical enantioselective N-selective nitroso aldol reaction of α-methylmalonamates with a nitrosoarene is reported. The reaction employs the Takemoto thiourea catalyst for the induction of enantioselectivity, and the corresponding optically acti

An interesting substrate-controlled reactivity switch has been observed in the reaction of α-fluoro-β-ketoamides with arynes. The reaction of secondary α-fluoro-β-ketoamides with arynes provided access to α-aryl-α-fluoroacetamides through an ar
