This research discusses a dichotomy in the additions of organolithiums and lithium amides to cyclobutenediones, resulting in different products. The distinct mode of ring scission allows for the synthesis of 2-oxobut-3-enamides and tetrasubstituted furans.
A dichotomy between the additions of organolithiums and lithium amides to cyclobutenediones is described wherein the former give carbonyl addition products while the latter induce ring opening by enone cleavage via O- to C-lithium transfer. This distinct mode of ring scission gives access to 2-oxobut-3-enamides and tetrasubstituted furans.
