First total synthesis of the polyhydroxy 5,6-dihydro-2H-pyrone containing natural products monticolide A and B is reported from tartaric acid. Key reaction is the iridium catalysed redox reaction of the Achmatowicz reaction product to the 5,6-dihydro-2H-pyrone moiety and the use of tartaric acid as a four hydroxy four carbon synthon.
由酒石酸报道了含多羟基5,6-二氢-2H-吡喃酮的天然产物山梨内酯A和B的首次全合成。关键反应是Achmatowicz反应产物与5,6-二氢-2H-吡喃酮部分的铱催化氧化还原反应,以及使用酒石酸作为四羟基四碳合成子。
