Abstract

Abstract Conditions have been found for the successful Birch reduction and reductive alkylation of N-alkyl arylsulphonamides, specifically in the naphthalene series. The derived C-alkylation products smoothly fragment on heating with re-aromatisation, affording a new specific route to 1-substituted naphthalenes starting from the 1-sulphonamides, and to both 2-mono-substituted and 2, 4-(or 1, 3-) disubstituted naphthalenes from the corresponding ...
