Ethyl 2-oxo-1-(2-oxopropyl)-1-cyclopentanecarboxylate, on treatment with tBuOH-tBuOK at rt (1h), affords unusual ring expansion products ethyl 3,5-dioxo-1-cyclooctanecarboxylate, ethyl 4-acetyl-3-oxo-1-cyclohexanecarboxylate and ethyl 2-acetyl-3-oxo-1-cyclohexanecarboxylate in 19, 40 and 12% yields, respectively.
Approaches to the synthesis of a novel family of carbocyclic nucleosides of potential anti-HIV interest have been developed. The key carbocyclic intermediate 9 was coupled with desired heterocyclic bases to give the corresponding bicyclic nucleosides. The structure of compound 9 and the bicarbocyclic dideoxynucleosides were confirmed by extensive 1H and 13C NMR studies including COSY, NOESY, DEPT and
已经开发了潜在的抗HIV兴趣的新型碳环核苷家族的合成方法。将关键的碳环中间体9与所需的杂环碱基偶联,得到相应的双环核苷。通过广泛的1 H和13 C NMR研究(包括COSY,NOESY,DEPT和选择性INEPT实验),证实了化合物9和双碳环双脱氧核苷的结构。
Stereoselectivity in reactions of bicyclo[3.3.0]oct-1-enes
The derivatives of trans-bicyclo[3.3.0]octane 3 and 6 have been obtained the bicyclo[3.3.0]oct-1-enes, sterically hindered at the exo-side, via photoinduced [2+2]cycloaddition of 1 with ethylvinyl ether and by hydroboration-oxidation of 5d, respectively.
