STEREOSELECTIVE ADDITIONS TO CARBOXYLIC ACID DIANIONS AND β-LACTONE SUBSTITUTED ESTER ENOLATES. APPLICATION TO THE SYNTHESIS OF RACEMIC EPI-BLASTMYCINONE, δ-MULTISTRIATINE, PARACONIC ESTERS AND LIGNANTYPE DILACTONES

New stereoselective syntheses are reported for racemic 4-epi-blastmycinone (6) and δ-multistriatine (13) utilizing the anti-configurated γ,δ-unsaturated β-hydroxy-carboxylic acids 2a/b.A diastereo- and enantioselective aldoltype addition of phenylacetic acid dianion to benzaldehyde has been achaived by employing optically active alkoxide amide bases.Finally, highly stereocontrolled additions to the novel β-lactone substituted ester enolates 22 are described.
