  Cycloaddition of 1-Methoxy-3-trimethylsilyloxybutadiene with Halogenated Carbonyl Compounds

  摘要：

  Cycloadditions of 1-methoxy-3-trimethylsilyloxy-1,3-butadiene (1) with halogenated carbonyl compounds (2) yielded corresponding substituted tetrahydro- and/or dihydropyran-4-ones (3 and/or 4). Lewis acids were found to be effective as catalysts. Reactions with less reactive carbonyl compounds (2c,d) afforded p-hydroxyacetophenone (5) produced by cyclodimerization of 1. Stereochemistry of the adducts was deduced by H-1 nmr spectroscopy.
