一种新的碱促进的6-(1,1-二甲基乙氧基)-2H-吡喃-3-酮异构化为4-(1,1-二甲基乙氧基)-5-羟基-2-环戊烯酮用于制备2-溴-5-[(1,1-二甲基乙基)二甲基甲硅烷氧基]-4-羟基-2-环戊烯酮,其是一种用于合成新制癌菌素和凯达西定发色团的潜在中间体。
A new base promoted isomerisation of 6-(1,1-dimethylethoxy)-2H-pyran-3-one to 4-(1,1-dimethylethoxy)-5-hydroxy-2-cyclopentenone is used in the preparation of 2-bromo-5-[(1,1-dimethylethyl)dimethylsilyloxy]-4-hydroxy-2-cyclopentenone, a potential intermediate for use in the synthesis of Neocarzinostatin and Kedarcidin chromophores.
