  • Synthesis and Conversions of Substituted <i>o</i>-[(Trimethylsilyl)methyl]benzyl <i>p</i>-Tolyl Sulfones to <i>o</i>-Quinodimethanes and Products Thereof
    作者:Brian D. Lenihan、Harold Shechter
    DOI:10.1021/jo970592c
    日期:1998.4.1
    Use of o-[(trimethylsilyl)methyl]benzyl p-tolyl sulfone (3) for synthesis and cycloaddition of substituted o-quinodimethanes has been investigated. Sulfone 3 is prepared from 2-methylbenzyl alcohol (4) by reactions with n-BuLi and chlorotrimethylsilane to form o-[(trimethylsilyl)methyl]benzyl alcohol (7) which phosphorus tribromide converts to o-[(trimethylsilyl)methyl]benzyl bromide (8). Displacement of 8 with sodium p-toluenesulfinate yields 3. Sulfone 3 is alkylated at its alpha-sulfonyl position upon deprotonation with n-BuLi followed by methyl iodide, ethyl, butyl, allyl, and benzyl bromides, and 5-bromo-1-pentene, respectively. Acylations occur using acid chlorides. Dialkylation occurs upon further reaction with n-BuLi and an alkyl halide. 1,4-Eliminations of alpha,alpha-dialkyl sulfones 11 with tetrabutylammonium fluoride (TBAF) give alpha,alpha-dialkyl-o-quinodimethanes (29); 3 is therefore a synthon for the o-quinadimethane-alpha,alpha-dianion (34). o-Quinodimethanes 29 undergo (1) cycloaddition with acrylonitrile, acrylate esters, and alkyl fumarates to yield 1,1-disubstituted-tetrahydronaphthalenes (30) and (2) 1,5-sigmatropic rearrangements of hydrogen to give styrenes (32). The stereochemistries of the various cycloadditions reveal significant mechanism information.
