Abstract

Chloromethylboryl-N-tosylhydrazone (CMBT) has been synthesized as a reagent to generate a diverse range of molecular skeletons. CMBT can undergo a series of transformations involving nucleophilic substitution of the chloride, coupling of the N-tosylhydrazones, follwed by boryl group functionalization. We further demonstrated that this CMBT reagent could enable a diverisity-oriented synthesis.
