Аннотация

In this review, we discuss the use of the nitrile function in the synthesis of cyclic sulfonamides (sultams), an important class of antibiotics. The cyano group is a versatile building block in sultam synthesis. It can form the sultam and sulton skeleton or activaten adjacent positions. Commonly, the nitrile group undergoes the carbanion-mediated sulfonate (sulfonamide) intramolecular cyclization reaction, acting as an electrophilic center attacked by a carbanion, forming enamines. Nitriles also facilitate substitutions at α-position through alkylation or cyclization and activate unsaturated bonds in various cycloadditions. Literature indicates that the nitrile group, as a methyleneamine precursor, shows promise for sultam synthesis. This method could efficiently produce spirocyclic sultams with applications in chemistry and biology.
