从厚壳桂(Cryptocarya laevigata)的叶和枝的CH_3OH-CH_2Cl_2(1:1)提取物(N 025439)中分离得到8个新化合物,其中1-8.基于广泛的1D和2D NMR光谱数据检查,新的δ-内酯衍生物1-6是含有独特的螺[3.5]壬烯基部分的单叔醇-聚酮杂化物。它们的俗名,cryptolaevilactones G-L,遵循相关已知的部分萜类cryptolaevilactones A-F。Cryptolaevilactone L(6)含有11,12-顺式取代基,而其它cryptolaevilactone含有反式取代基。通过各种光谱数据分析表征了线性δ-内酯7(cryptolaevilactone M)的结构,并通过立体选择性烯丙基化和Grubbs烯烃复分解的全合成确定了其绝对构型。化合物8被阐明为具有3,4-顺式二醇官能团的紫罗兰酮衍生物。
A CH3OH–CH2Cl2 (1:1) extract (N025439) of the leaves and twigs of Cryptocarya laevigata furnished eight new compounds, 1–8. Based on extensive 1D and 2D NMR spectroscopic data examination, the new δ-lactone derivatives 1–6 are monoterpene–polyketide hybrids containing a unique spiro[3.5]nonenyl moiety. Their trivial names, cryptolaevilactones G–L, follow those of the related known meroterpenoids cryptolaevilactones A–F. Cryptolaevilactone L (6) contains 11,12-cis-oriented substituents, while the other cryptolaevilactones contain trans-oriented groups. The structure of the linear δ-lactone 7, cryptolaevilactone M, was characterized from various spectroscopic data analysis, and the absolute configuration was determined by total synthesis through stereoselective allylation and Grubbs olefin metathesis. Compound 8 was elucidated to be an ionone derivative with a 3,4-syn-diol functionality.
