The Reaction between Tert-Butyl Isocyanide and Acetylenic Esters in Presence of 2-Thenoyltrifluoroacetone: A Synthesis of Highly Functionalised 4 H -Pyrans †
Tert-butyl isocyanide reacts with dialkyl acetylenedicarboxylates in the presence of 2-thenoyltrifluoroacetone to yield 4H-pyran derivatives in good yields.
