B. Danieli et al., FIRST ENANTIOSELECTIVE SYNTHESIS OF (-)-AKAGERINE BY A CHEMOENZYMATICAPPROACH, Journal of organic chemistry, 60(8), 1995, pp. 2506-2513
(-)-Akagerine (1) was synthesized in an efficient and stereocontrolled
fashion from the readily available (1S,2R)-cyclohexenedimethanol mono
acetate 4. Key steps were the cleavage of the C(17)/C(18) bond of 14a
and the regio- and stereoselective cyclization of the dialdehyde 16 to
give the tetracyclic skeleton of akagerine.
