ASYMMETRIC TOTAL SYNTHESIS OF NATURAL (-)- AND UNNATURAL (+)-STEGANACIN DETERMINATION OF THE ABSOLUTE CONFIGURATION OF NATURAL ANTITUMOR STEGANACIN

A virtually complete asymmetric control in the synthesis of 2,3-disubstituted butan-4-olide (10) was demonstrated by employing the butenolide (12) as the chiral acceptor for the conjugate 1,4-addition.Highly efficient asymmetric total synthesis of natural (-)- and unnatural (+)-steganacin was accomplished.The absolute stereostructure of natural antitumor steganacin was determined to be 1.

FIRST ASYMMETRIC TOTAL SYNTHESIS OF (+)-STEGANACIN. DETERMINATION OF ABSOLUTE STEREOCHEMISTRY

(+)-Steganacin was synthesized in a new and highly specific asymmetric pathway based on the novel application of chiral γ-lactone as a chiral synthon.By this synthesis the absolute stereochemistry of natural (-)-steganacin could be determined in unequivoc
