  • Thermolytic rearrangements of 1,1-cyclopropanedimethanol disulfonates: cyclopropylcarbinyl cations revisited
    作者:Peter A. Wade、Paul A. Kondracki
    DOI:10.1021/jo00063a039
    日期:1993.5
    1,1-Cyclopropanedimethanol dimethanesulfonate (1a) and the corresponding ditosylate lb underwent thermal rearrangement at 110-140-degrees-C after melting. Short reaction time resulted in the formation of mixtures containing 1-(sulfonyloxy)cyclobutanemethanol sulfonates 5a,b (major), starting material, and 2-methylene-1,4-butanediol disulfonates 6a,b. Longer reaction times afforded complete conversion to disulfonates 6a,b, isolated in 49 and 62 % yield, respectively. These reactions are postulated to proceed via initial carbocation formation, presumably interconverting bicylobutonium and cyclopropylcarbinyl cations, which exist as ion pairs in the melt. Crossover experiments with dimesylate la and ditosylate lb offer support for the presence of ion pairs in the melt: internal return competed with external trapping of the intermediate cations. Reaction of la and 2-methylene-1,4-butanediol ditosylate (6b) gave a mixture in which 2-methylene-1,4-butanediol 1-mesylate 4-tosylate (8) predominated over the isomeric 4-mesylate 1-tosylate 7 by a 5:1 ratio. Crossover experiments with 6a and 6b indicated that partial allylic substitution was occurring for the open-chain products under the thermolysis conditions. Reaction of la with excess tetrabutylammonium tosylate at 114-15-degrees-C afforded mixed 1-(sulfonyloxy)cyclobutanemethanol sulfonates and 2-methylene-1,4-butanediol disulfonates formed competitively by internal return and tosylate interception. Acetolysis of la at 42-43-degrees-C afforded predominately products of internal return early on the reaction profile. Longer reaction times afforded predominately monoacetates while reactions run at 108-10-degrees-C afforded substantial amounts of diacetates. Acetolysis of 1-acetoxycyclobutanemethanol mesylate (12a) resulted in the substitution of the mesyloxy group with substantial rearrangement.

  • A Spiroalkylation Method for the Stereoselective Construction of α-Quaternary Carbons and Its Application to the Total Synthesis of (<i>R</i>)-Puraquinonic Acid
    作者:Adam A. H. Elmehriki、James L. Gleason
    DOI:10.1021/acs.orglett.9b03887
    日期:2019.12.6
    Cyclic α-quaternary carbon stereocenters were prepared from biselectrophillic substrates and an easily prepared chiral bicyclic sulfonyl lactam. This was achieved in two steps by spiroalkylation, employing biphasic reaction conditions with a phase-transfer catalyst, followed by reduction and alkylation with a series of alkyl halide electrophiles. The products of this method were isolated in good yields

  • The Regiochemistry of Cyclization of α-Sulfenyl-, α-Sulfinyl-, and α-Sulfonyl-5-hexenyl Radicals:  Procedures Leading to Regioselective Syntheses of Cyclic Sulfones and Sulfoxides
    作者:Ernest W. Della、Sean D. Graney

    日期:2004.5.1
    quantities of 6-endo product, the α-sulfinyl species cyclizes with high selectivity (95.5:4.5) via a 5-exo mode. By contrast, ring closure of the 5-methyl-5-hexenyl radicals is found to give substantially the 6-endo product in all cases. It is the α-sulfonyl-5-methyl-5-hexenyl radical that now exhibits high regioselectivity (97.5:2.5) for 6-endo closure: an illustration of the synthetic value of this observation
