A three-step approach to the synthesis of sp 3-enriched β-fluoro sulfonyl chlorides starting from alkenes is reported. The method was successfully applied to a wide range of acyclic and cyclic substrates, bearing either an exocyclic or an endocyclic double bond. The procedure worked with a wide range of substrates and tolerated a number of functional and protecting groups. Moreover, the target cyclic compounds were obtained as single cis diastereomers on a multigram scale. The title compounds are promising building blocks for drug discovery that can be used to obtain sp 3-enriched β-fluoro and α,β-unsaturated sulfonamides.

Two hydrophilic spiroalkenes, azaspiro[2.3]hex-1-ene and azaspiro[2.4]hept-1-ene, were designed and synthesized. Compared to the previously reported spiro[2.3]hex-1-ene, the azaspiroalkenes exhibited greater water solubility and reactivity as dipolarophiles in the photoinduced tetrazole-alkene cycloaddition reaction. In addition, an azaspiro[2.3]hex-1-ene-containing amino acid, AsphK, was found to be charged by an engineered pyrrolysyl-tRNA synthetase into proteins via amber codon suppression in E. coli as well as in mammalian cells.
