Abstract
- 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.
