Prostanoids: LXXXVIII. Chlorocyclopentenone Building Blocks in the Synthesis of Marine Prostanoids
摘要:
Starting from 2,3-dichloro-4,4-ethylenedioxy-2-cyclopentenone, a practical procedure has been developed for the synthesis of a series of 4-substituted 2-chloro-4-hydroxycyclopentenones.

stereospecific formal synthesis of clavulones , prostanoids of marine origin, has been accomplished starting from tricyclo[5.2.1.02,6]decadienone epoxide . Reaction with oct-2-ynyl zinc bromide, followed by reductive epoxide ring opening and subsequent thermal cycloreversion, usingflashvacuumthermolysis, leads to λ-hydroxycyclopentenone , an essential builing block for clavulones I and II, in an excellent
