  摘要：

  4-羟基或/和5-羟基-(2E)-烯酸盐的碱性水解后进行酸处理，得到了相应的(2E)-烯酸，然后未经过进一步纯化直接进行内酯形成反应。粗酸与2,4,6-三氯苯甲酰氯在吡啶中反应，分别生成γ-内酯或δ-内酯，并伴随有反-顺异构化。通过这种方法合成了(±)-(4,5)-反-5-苄氧基-2-己烯-4-内酯（整体产率90%）、(S)-5-羟基-2-戊烯-4-内酯（整体产率86%）、(4S,5R)-5-羟基-2-己烯-4-内酯（整体产率86%）、(4R,5S)-5-羟基-2-己烯-4-内酯（整体产率82%）、(S)-伐索酸（整体产率58%）以及天然产物(5R,7S)-7-羟基-2-辛烯-5-内酯（优蔬内酯：整体产率20%）。

  Macrosphelides E–I have been isolated, along with known macrosphelides A and C, from a strain of Periconia byssoides originally separated from the sea hare Aplysia kurodai, and the absolute stereostructures of macrosphelides E–G and I have been elucidated on the basis of spectroscopic analyses using 1D and 2D NMR techniques and some chemical transformations. In addition, the absolute configuration of macrosphelide C, previously undetermined, has been established by X-ray analysis and application of the modified Mosher method. Macrosphelides E–H inhibited the adhesion of human-leukaemia HL-60 cells to HUVEC.

  宏球苷E–I与已知的宏球苷A和C一起从最初从海兔Aplysia kurodai分离出的Periconia byssoides菌株中提取出来，并且宏球苷E–G和I的绝对立体结构已通过使用1D和2D NMR技术的光谱分析及一些化学转化进行阐明。此外，之前未确定的宏球苷C的绝对构型已通过X射线分析和改良的Mosher方法确立。宏球苷E–H抑制了人类白血病HL-60细胞与HUVEC的粘附。

  Alkaline hydrolysis of 4-hydroxy- or/and 5-hydroxy-(2E)-alkenoate followed by acid treatment gave the corresponding (2E)-alkenoic acids which were subjected to lactone formation reaction without further purification. The crude acids were treated with 2,4,6-trichlorobenzoyl chloride in pyridine to afford γ-lactone or δ-lactone, respectively, accompanied by trans–cis isomerization. By this procedure, (±)-(4,5)-trans-5-benzyloxy-2-hexen-4-olide (90% overall yield), (S)-5-hydroxy-2-penten-4-olide (86% overall yield), (4S,5R)-5-hydroxy-2-hexen-4-olide (86% overall yield), (4R,5S)-5-hydroxy-2-hexen-4-olide (82% overall yield), (S)-parasorbic acid (58% overall yield) and natural product, (5R,7S)-7-hydroxy-2-octen-5-olide (euscapholide: 20% overall yield) were synthesized.
