AbstractA three-step approach to the synthesis of sp3-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 sp3-enriched β-fluoro and α,β-unsaturated sulfonamides.

Parameter Temperature Dependence

Rates of solvolysis of methanesulfonyl chloride and benzenesulfonyl chloride have been determined in H2O and D2O. The free energy, enthalpy, entropy, and heat capacity of activation were calculated. The exceptional accuracy of the data permitted an estimation of dΔCp≠/dT from a four parameter temperature dependence of the kinetic rates.From these data we conclude that both sulfonyl chlorides hydrolyse by the same mechanism (Sn2) The change in R from CH3 to C6H5 in RSO2Cl did not alter ΔCp≠ but ΔS≠ (20°) was changed from −8.32 to −13.25 cal deg−1 mole−1, respectively. The significance of this difference is attributed to the probability of bond formation rather than to differences in solvent reorganization.

Proton Source

The α-halo-β-ketosulfonyl functionality was attacked by ethanethiolate at the halogen which, in the presence of a proton source, usually resulted in reduction to the β-ketosulfone. A range of other soft nucleophiles did not react, whereas hard nucleophiles invariably attacked at the carbonyl, with subsequent cleavage to α-halosulfones. Ambident arylsulfinate anions usually attacked at halogen to form the sulfonyl halide, which reacted with excess sulfinate to give an intermediate that is readily attacked by alcohols. This reaction resulted in the formation of alkyl arylsulfinate esters in reasonable yields. The same reaction occurred when sulfonyl chlorides were reacted with sulfinate salts and it was rationalized by using HSAB principles. Spectral properties of some sulfinate esters are presented.
