标题:Ambient Temperature Method For The Generation And Diels-alder Trapping Of Benzofuran-2,3-Quinodimethane (2,3-Dimethylidene-2,3-Dihydrobenzofuran)
摘要:The Ito-Saegusa Method Has Been Used To Generate Benzofuran-2,3-Quinodimethane 10 From The Corresponding Silyl Acetate 17B In Solution At-4 Degrees C. The Intermediate Reacts Efficiently With A Range Of Reactive Diels-Alder Dienophiles With Moderate To Good Levels Of Regioselection; The Structure Of The Major Diastereoisomer Has Been Determined By X-Ray Analysis.
