Total synthesis of (−)-sporochnol A, the fish deterrent, from a chiral malonate
摘要:
From a single chiron, the homochiral benzylic malonic acid ester (R)-(+)-2 available with high enantiomeric excess by enzymatic hydrolysis (PLE acetonic powder), enantiomerically pure (-)-sporochnol A 1 was prepared. This versatile method allows preparation of sporochnol 1, via aldehydes 7 and 15, in good overall yield. (C) 1999 Elsevier Science Ltd. All rights reserved.

From a single chiron (R)-4, available with high enantiomeric purity (96%) by simple enzymatic hydrolysis (PLE) of a prochiral malonate, were prepared convenient precursors of the two enantiomers of alpha- and beta-cuparenones (1a,b and 2a,b). This versatile method also allows preparations of the enantiomer (S)-4 and dimethyl 2-methyl-2-p-tolylsuccinate ((S)-9a), as well as the new butyrolactones (R)-15, (R)-23, and (S)-25, the new but-3-enolide (S)-32, and cyclopentenones (S)-22 and (S)-30, all these compounds bearing an asymmetric quaternary carbon.
