H. Toshima et al., ASYMMETRIC TOTAL SYNTHESES OF (-CORONAFACIC ACID AND (+)-CORONATINE()), Bioscience, biotechnology, and biochemistry, 61(4), 1997, pp. 752-753
An asymmetric total synthesis of (+)-coronafacic acid, starting from (
R)-(+)-3-acetoxy-2-cyclopen-1-one as a chiral source, was accomplished
, Construction of the 1-hydrindanone framework was carried out by usin
g intramolecular 1,6-conjugate addition as the key step, Coupling betw
een (+)-coronafacic acid and protected coronamic acid, and subsequent
deprotection provided (+)-coronatine, This is the first asymmetric tot
al synthesis of (+)-coronatine.
