A synthesis of di-, tri- and tetra-substituted furans from reaction of the corresponding ketones and α-haloketones with LiHMDS is reported. Reaction under continuous-flow conditions gave increased yields and removed the need for external cooling when compared to the unoptimised batch conditions.
据报道,由相应的酮和α-卤代酮与LiHMDS的反应合成了二,三和四取代的呋喃。与未优化的分批条件相比,在连续流动条件下的反应可提高收率,并且无需外部冷却。
