N-Benzoyl- and N-arylsulfonyl-p-benzoquinone-mono-imine ketals (QIKs) undergo smooth Diels-Alder cycloadditions with typical 1,3-butadienes to yield the expected endo adducts. Treatment with catalytic acid rapidly converts the adducts to dihydronaphthalen
The Diels-Alder reactions of quinone imine ketals: A versatile synthesis of highly substituted 5-methoxyindoles
Banfield, Scott C.,England, Dylan B.,Kerr, Michael A.
, p. 3325 - 3327 (2007/10/03)
Equation presented 32-71% overall N-Benzoylated quinone imine ketals undergo smooth cycloadditions in a [4 + 2] sense to yield the expected cycloadducts. The crude cycloadducts, when subjected to a short series of simple transformations, produce synthetic
