Abstract A rational synthesis of Spiro bicyclo (5,4) dec-2-ene-3-methyl-1,6-dione (1) and Spiro bicyclo (5,5) undec-2-ene-3-methyl-1,7-dione (2) from 2-acetyl cycloalkanone is described. Compounds (1) and (2) have very high potentials as important precursors to many naturally occurring bridged tricyclic compounds. A single crystal X-ray crystallographic study of compound (2) was carried out to establish
摘要 Spiro bicyclo (5,4) dec-2-ene-3-methyl-1,6-dione (1) and Spiro bicyclo (5,5) undec-2-ene-3-methyl-1的合理合成,描述了来自 2-乙酰基环烷酮的 7-二酮 (2)。化合物 (1) 和 (2) 作为许多天然存在的桥连三环化合物的重要前体具有非常高的潜力。进行化合物(2)的单晶X射线晶体学研究以确定结构,因为化学和光谱方法证明相当不充分。
