Organophosphorus Chemistry, 18 - The Reaction of 1,8-Naphthosultam with Alkyl Phosphites and Chlorinated Phosphorus Reagents

Trialkyl phosphites (2a-c) react with 1,8-naphthosultam (6) to give the respective N-alkylated products 7a-c.Compounds 7a-c were also prepared by the action of dialkyl phosphites on 6 in the presence of p-TsOH.Moreover, 7a could be obtained by treating 6 with DMMP (8).On the other hand, chlorinated phosphorus reagents (11) condense with 6 to give products of type 12.Structures of the new products were assigned according to consistent analytical and spectroscopic measurements.
