A novel approach to 3-polyfluoroalkyl pyrroles is reported based on step by step reactions: 1,2-addition of Me3SiCN to β-alkoxyvinyl polyfluoroalkyl ketones, reduction with LiAlH4 and subsequent hydrolysis with intramolecular cyclization. The hydrolytic instability of various polyfluoroalkyl groups at position 3 of the pyrrole ring was evident and a pathway for the hydrolysis was proposed.
据报导一种基于逐步反应的3-多氟烷基吡咯的新颖方法:将Me 3 SiCN 1,2-加成至β-烷氧基乙烯基多氟烷基酮,用LiAlH 4还原并随后通过分子内环化进行水解。在吡咯环的3位上的各种多氟烷基的水解不稳定性是明显的,并提出了水解的途径。
