A series of Piloty’s acid derivatives were easily prepared under mild and neutral conditions. The ease of isolation of the final product offers a marked advantage over well-known procedures. This methodology is particularly attractive as it cleanly provided low molecular weight aliphatic sulfohydroxamic acids, which are very interesting for their tendency to generate HNO under physiological conditions.
sulfonamides as sulfenylating agents has been established. In the presence of catalytic amounts of iodine and N-hydroxysuccinimide, N-hydroxy sulfonamides participated in sulfenylation with indoles, 7-azaindole, N-methyl pyrrole, and 2-naphthol to afford structurally diverse thioethers in moderate to excellent yields with very high regioselectivity.
