N-Functionalization of 1,2-Azaborines

General protocols for the N-functionalization of 1,2-azaborines with C(sp3), C(sp2), or C(sp) electrophiles are described. The syntheses of a new parental BN isostere of trans-stilbene and a BN isostere of a lisdexamfetamine derivative were accomplished with the developed methodology.

Sulfoximines as S-Aryl Surrogates: A Photocatalytic Rapid, Metal-Free, Mild Protocol to Access 3-Arylsulfenyl Indoles

Sulfoximines as S-aryl surrogates permit the preparation of 3-arylsulfenylindoles through reaction with indoles in the presence of I2 under visible-light irradiation. This environmentally friendly approach is fast, mild, metal-, photocatalyst-, additive-, and oxidant-free, and it provides the desired products in moderate to good yields with a wide substrate scope.
