Popis: | Prostaglandins and Prostaglandin Intermediates. VIII. Synthesis of (1S, 5S)-5-Methyl-2-oxa-bicyclo[3.3.0]octane-3,6-dione, an Important Intermediate for 8-Methylprostaglandin C2 The bicyclic lactone 5 is prepared by Meerwein-Ponndorf-Verley-reduction of the chiral cyclopentyl acetic acid 3. The stereoselectivity of this reaction is compared with that of complex metal hydride reductions. |
