Feist–Benary furan synthesis has been developed that involves a lithium aldol reaction between a methyl ketone and an α-chloroaldehyde followed by a thermally induced tetrahydrofuran formation/dehydration sequence and affords 2,5-disubstituted furans in good overall yield. This process is demonstrated on multigram scale and is amenable to the production of symmetric or asymmetric furans that incorporate
已经开发了一种改进的 Feist-Benary 呋喃合成,它涉及甲基酮和 α-氯醛之间的锂醇醛反应,然后是热诱导的四氢呋喃形成/脱水序列,并以良好的总产率提供 2,5-二取代呋喃。该过程在多克规模上得到证明,并且适用于生产包含一系列取代基(例如,芳基、叔丁基、二茂铁基)的对称或不对称呋喃。
