Synthesis of 3-aminocyclobutenones via [2 + 2] cycloaddition of ynamides and ketenes
(Massachusetts Institute of Technology, 2012)
Ynamides react with various classes of ketenes in intermolecular [2 + 2] cycloaddition to afford substituted cyclobutenones with complete regioselectivity. The cycloaddition substrates are easily assembled from amine ...
