[reaction: see text] Intramolecular cyclopropanation of a carbene engendered from the corresponding diazo beta-ketoester produced the desired bicyclo[3.1. 0]hexane pseudosugar. Purine nucleosides obtained via Mitsunobu coupling were resolved with adenosine deaminase. The requisite beta-ketoester was assembled in one step from ethyl acetoacetate and acrolein.
[反应:见正文] 由相应的重氮β-酮酯产生的卡宾进行分子内环丙烷化反应,生成了所需的双环[3.1.0]己烷假糖。通过 Mitsunobu 偶联得到的嘌呤核苷用腺苷脱氨酶进行拆分。所需的β-酮酯由乙酰乙酸乙酯和丙烯醛一步合成。
