✦ Synopsis
Note on the Synthesis of (E)‐12‐Hydroxy‐10‐heptadecenoic Acid, (5__E__, 10__E__)‐12‐Hydroxy‐5, 10‐heptadienoic Acid and (5__Z__, 10__E__)‐12‐Hydroxy‐5,10‐heptadienoic Acid
The syntheses of two heptadecadienoic and one heptadecenoic acid, compounds which formally may be derived from prostaglandin‐like molecules by removal of a C~3~‐fragment from the five‐membered ring, are described.
