The first example of a chiral halogen-bond donor with a sp3-hybridized carbon–iodine moiety in a fluorobissulfonyl scaffold is described. The binaphthyl backbone was designed as a chiral source and the chiral halogen-bond donor (R)-1 was synthesized from (R)-1,1′-binaphthol in 11 steps. An NMR titration experiment demonstrated that (R)-1 worked as a halogen-bond donor. The Mukaiyama aldol reaction
描述了在氟双磺酰基支架中具有 sp3 杂化碳碘部分的手性卤素键供体的第一个例子。联萘骨架被设计为手性来源,手性卤素键供体 (R)-1 由 (R)-1,1'-联萘酚分 11 步合成。核磁共振滴定实验表明 (R)-1 作为卤素键供体。Mukaiyama 羟醛反应和喹啉还原使用 (R)-1 作为催化剂进行检查以评估不对称诱导。
