  Stereoselective Synthesis of (+)-Goniothalesdiol

  摘要：

  Stereoselective synthesis of antitumor tetrahydrofuran (+)-goniothalesdiol was achieved in high overall yield from (-)-D-tartaric acid. Key features include an FeCl3 mediated THF formation with very high selectivity. Synthesis of natural gonithalesdiol and its analogue 2,5-bis-epi-goniothalesdiol was achieved from a common intermediate.

  Stereoselective Total Synthesis of Bioactive Styryllactones (+)-Goniofufurone, (+)7-epi-Goniofufurone, (+)-Goniopypyrone, (+)-Goniotriol, (+)-Altholactone, and (−)-Etharvensin

  摘要：

  [GRAPHICS]Stereoselective total synthesis of biologically active styryllactones 7-epi-goniofufurone, goniofufurone, goniopypyrone, goniotriol, altholactone, and etharvensin was achieved in high overall yields from a common intermediate derived from D-(-)-tartaric acid. It is based on the utility of a masked tetrol, comprising an alkene tether and four contiguous hydroxy groups. The pivotal reaction sequence involves hydroxy-directed lactonization via the oxidation of alkene, and subsequent elaboration to styryllactones. The masked tetrol was prepared by the extension of gamma-phenyl-gamma-hydroxy butyramide, readily obtained from the bis-dimethylamide of tartaric acid, employing a combination of selective Grignard additions and a stereoselective reduction.
