Cyclobutyl sulfones are obtained by reduction of bicyclobutyl sulfones with lithiumaluminium hydride and these may be used in further synthetic transformations, as illustrated by the synthesis of rac-junionone.

Addition of hydrazoicacid or benzylamine to 1-(arylsulfonyl) bicyclobutanes introduces the nitrogen nucleophlle at position 3 of the derived cyclobutane, even when a carboxyl derivative is present at this position as a second activating group. Precursors of α-amino cyclobutane carboxylic acids may thus be obtained and these can be further transformed to the title diacids via carbonylation α to the
