  • Cycloaddition and Oxidation Reactions of a Stable Thioaldehyde, (2,4,6-Tri-<i>t</i>-butyl)thiobenzaldehyde
    作者:Soichiro Watanabe、Toshio Yamamoto、Takayuki Kawashima、Naoki Inamoto、Renji Okazaki
    DOI:10.1246/bcsj.69.719
    日期:1996.3
    The title thioaldehyde 1 undergoes [4 + 2] cycloaddition with 2,3-dimethyl-1,3-butadiene at 160 °C and [3 + 2] cycloadditions with diphenylnitrilimine and mesitonitrile oxide at room temperature. The intermediary cycloadduct with mesitonitrile oxide undergoes cycloreversion to give 2,4,6-tri-t-butylbenzaldehyde and mesityl isothiocyanate as the final products. Oxidation of 1 with m-chloroperbenzoic acid (mCPBA) and dimethyldioxirane (9) gives a mixture of (E)- and (Z)-isomers of the corresponding S-oxides (sulfines), the former and the latter being kinetically and thermodynamically controlled products, respectively. Although both (E)- and (Z)-sulfines are not further oxidized by mCPBA, the (Z)-sulfine is oxidized with 9 to give 7-oxa-8-thia-2,4,6-tri-t-butylbicyclo[4.3.0]nona-2,4,9-triene 8,8-dioxide and 6,8-di-t-butyl-3,4-dihydro-4,4-dimethyl-1H-2-benzothiopyran 2,2-dioxide, both of which are intramolecular cyclization products of an intermediary thioaldehyde dioxide (sulfene).

    Title compounds were synthesized by the reaction of 2,4,6-tri-t-butylthiobenzaldehyde with some diazomethanes. The photolysis of the most sterically congested episulfide obtained from t-Bu2CN2 gave an unusual product resulting from 1,2-migration of t-butyl group instead of the corresponding styrene, a normal photo-product, the corresponding styrene, together with Dewar benzene and benzothiophene derivatives.
