NEW GENERATION AND CYCLOADDITION OF α-(N-TERT-BUTYLIMINO)-o-QUINODIMETHANE

Ito, Yoshihiko,Nakajo, Eiji,Saegusa, Takeo

, p. 5139 - 5142 (1984)

CsF induced 1,4-elimination of ammonium bromide, prepared by quaternization of N-tert-butyl o-(dimethylaminomethyl)benzimidoylsilane 6, provides a new generation of α-(N-tert-butylimino)-o-quinodimethane (3a), which gives benzocyclobutenone N-tert-butylimine (8) in the absence of dienophile.Trapping of 3a with electron deficient olefins affords Diels-Alder adducts regioselectively.
