Diazo transfer adjacent to a sulfoxide moiety to provide stable, isolable α-diazo-β-oxo sulfoxides has been achieved. Use of monocyclic and bicyclic sulfoxide precursors is critical in enabling isolation of stable derivatives, through introduction of conformational constraint, while acyclic α-diazo-β-oxo sulfoxides are too labile to isolate and characterize.
已经实现了与亚砜部分相邻的重氮转移,以提供稳定的,可分离的α-重氮-β-氧代亚砜。使用单环和双环亚砜前体对于通过引入构象约束条件分离稳定的衍生物至关重要,而无环α-重氮-β-氧代亚砜过于不稳定,无法分离和表征。
