Abstract3-Iodolevoglucosenone reacts with the sodium derivative of ethyl cyanoacetate at −60°C to give a tetrasubstituted cyclopropane derivative; similar reactions of the sodium derivatives of ethyl acetoacetate and acetylacetone at −60 °C afford the expected transformed Michael adducts, while at 20 °C,O,C-dialkylated products of the oxetene series are formed.
摘要3-碘代左旋葡萄糖酮在-60℃与氰基乙酸乙酯的钠衍生物反应生成四取代的环丙烷衍生物;乙酰乙酸乙酯和乙酰丙酮的钠衍生物在 -60 °C 下的类似反应提供了预期的转化迈克尔加合物,而在 20 °C 下,形成了氧杂环丁烷系列的二烷基化产物。
