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

In view of planned syntheses of target cyclobutane derivatives, a series of new 3-substituted bicyclobutanes was prepared from sulfones 1–7. Some novel addition reactions involving the central bond were then applied to several of the new compounds as well as to some previously described bicyclobutanes. These reactions include the additions of hydrazoic acid, of cyanocuprate reagents other than methyl
