A fragment library of electrophilic small heterocycles was characterized through cysteine-reactivity and aqueous stability tests that suggested their potential as covalent warheads.

The reaction of diazocyclopropane generated in situ with vinyl bromide occurs as regioselective 1,3-dipolar cycloaddition to give 5-bromospiro(1-pyrazoline-3,1'-cyclopropane) in similar to 60% yield. Reactions of the latter with nucleophilic reagents, which can occur both with retention and opening of the cyclopropane ring, were studied.
