boronate complex which, upon N-protonation with acetic acid, undergoes 1,2-migration with cleavage of the central C-N bond to relieve ring strain. The methodology is applicable to primary, secondary, tertiary, aryl, and alkenyl boronic esters and occurs with complete stereospecificity. The homologated azetidinyl boronic esters can be further functionalized through reaction of the N-H azetidine, and through
