compounds include enones and enals, but also
carboxylic acids and the

organic chemistry,
enone–alkene
cycloadditions are a
version of the [2+2] cycloaddition. This
reaction involves an

serve as a
precursor for
regiospecific formation of an enolate, here the
enone is a "masked functionality"...

probable mechanisms are thus two possibilities: The
