Condensation of the title isocyanates with olefins and subsequent dissolving-metal reduction (sulphonyl derivatives) or chromatography on Florisil (trifluoroacetyl derivatives) gave several N-unsubstituted β-lactams including two 8-aza-2-oxabicyclo[4.2.0]octan-7-one derivatives.

Abstract The deconstructive reorganization strategy for the synthesis of benzene-containing products from the kojic acid- and maltol-derived alkynes has been recently reported. In this strategy, kojic acid and maltol are analogous to the “Transformers”, which can transform into benzofurans and benzaldehydes via annulation reactions. Under the synthetic standpoint, this deconstructive reorganization
