A New and Efficient One-pot Synthesis of Trialkyl 6- tert -Butylamino-2 H -pyran-2-one-3,4,5-tricarboxylates

A New and Efficient One-pot Synthesis of Trialkyl 6- tert -Butylamino-2 H -pyran-2-one-3,4,5-tricarboxylates

The highly reactive 1:1 intermediate produced in the reaction between tert-butyl isocyanide and dialkyl acetylenedicarboxylates is trapped by dialkyl 2-bromomalonates to yield the title compounds in fairly high yields.
