  Total synthesis of (−)-ampullicin and (+)-isoampullicin two growth regulators from Ampulliferina Sp. No. 27

  摘要：

  The growth regulators (-)-Ampullicin (1) and (+)-isoampullicin (2) have been synthesized utilizing carbaldehyde (25) as the chiral source and N-tertbutoxycarbonyl-3-methyl-2-(trimethylsiloxy)pyrrole (33) as the five-carbon homologative reagent. The synthesis of (1) and (2) is discussed in the context of retrosynthetic analysis. Carbaldehyde (25), has been prepared from both enantiomers of carvone, either (7) or (9), by application of a 15-step sequence with 4.7% and 5.4% overall yields respectively.

  Pinthunamide (1), a sesquiterpene metabolite produced by a fungus Ampulliferina sp., was synthesized by starting from (1R,4S,6S)-6-hydroxy-1-methylbicyclo[2.2.2]octan-2-one (4), which could readily be prepared by yeast reduction of the corresponding ß-diketone 5.

  Pinthunamide (1)是一种倍半萜类代谢产物，由真菌Ampulliferina sp.产生，由(1R,4S,6S)-6-羟基-1-甲基双环[2.2.2]辛烷-2-酮(4)合成，而(4)可通过酵母还原相应的β-二酮5来制备。
