  Regioselectivity and yields of Yamaguchi cyclization of (15S,16S)‐15,16‐dihydroxy‐otadecyl‐(6Z,9Z,12Z)‐trienoic acid and its saturated homologue have been compared at different temperatures and concentrations. For the unsaturated species the regioselectivity of cyclization depends on temperature to such an extent that the preferred regioisomer changes as the temperature changes, whereas for the saturated

  比较了在不同温度和浓度下（15S，16S）-15,16-二羟基十八烷基-（6Z，9Z，12Z）-三烯酸的山口环化的区域选择性和产率。对于不饱和物质，环化的区域选择性取决于温度，以至于优选的区域异构体随温度的变化而变化，而对于饱和的同系物，偶数环却始终是优选的。分子力学被用来解释这些发现。对于两种二羟基酸，有实验证据表明，与类似的单羟基内酯不同，两种单环区域异构体的产率是热力学控制的。不饱和一羟基酸的较高环化产率是根据构象预组织来解释的。
• Structure and Stereochemistry of Aplyolides A−E, Lactonized Dihydroxy Fatty Acids from the Skin of the Marine Mollusk <i>Aplysia depilans</i>

  The opisthobranch Aplysia depilans contains in its dorsum five unprecedented C-16 and C-18 fatty acid lactones (2-6). Their structures were assigned on the bases of chemical and spectral methods. Lactone 2 is derived by cyclization of 15(S)-hydroxyhexadeca-4(2),7(2),10(2),13(Z)-tetraenoic acid. The absolute stereochemistry at C-15 was determined by Mosher's method after opening of the lactone ring. Two other lactones (3 and 5) result from the cyclization either at C-15 or C-16 of 15,16-dihydroxyoctadeca-9(Z),12(Z)-dienoic acid. They differ from the remaining pair (4 and 6) by the absence of an additional double bond at C-6. S absolute stereochemistry of the free carbinols in 3-6 was suggested by applying Mosher's method. The same absolute stereochemistry was assigned at all lactonized carbinol centers by isomerization of the lactones by ring opening and subsequent enzymatic cyclization.
