Abstract

Results from efforts aimed at the synthesis of polyhydroxylated jatropha-5,12-dienes are unveiled. An apparently pre-qualified plot consisting of successive aldol addition and ring-closing metathesis was pursued in order to construct the fully oxidized trans-bicy­clo[10.3.0]pentadecane scaffold of naturally occurring jatrophanoids.

  • 15 All attempts to remove the PMB protecting group from either 9 or 10 under oxidative (DDQ) or reductive conditions met with failure. At prolonged reaction times or in the presence of an excess of DDQ in aqueous pH 7 buffer, we observed the formation of the corresponding C15 benzoates from 9 or 10.

  • 21 Upon warming, we observed cleavage of the silyl ether at C3.
  • 22 Our attempts to utilize a (c-Hex)2B(OTf)-mediated aldol reaction with the intend to exploit an 1,5-asymmetric induction failed to deliver the desired aldol 19. Instead, we isolated the PMB deprotected ketone 8 in varying amounts. This undesired outcome could be caused by impurities from our preparation and handling of (c-Hex)2B(OTf).

  • 27 In an explorative study, the enone 21 was reduced (NaBH4, CeCl3, MeOH) to the corresponding allylic alcohol (86%, 12 mg), which was subsequently converted (TBSOTf, 2,6-lutidine, CH2Cl2) into the corresponding silyl ether (84%, 13 mg). Neither the exposure of the allylic alcohol to 3b (0.2 equiv, toluene, 110 °C, 16 h) or 3c (0.05 equiv, toluene, 110 °C, 6 h) nor of the corresponding silyl ether to 3c (0.1 equiv, toluene, 110 °C, 4 h) yielded the desired RCM product.
  • 28 In an explorative study, the C10 OPMB ether was cleaved (DDQ) to provide the corresponding C10 allylic alcohol. Exposure of this triene to 3b (0.05 equiv, toluene, 110 °C, 3 h) only led to the isolation of the substrate (55%).
  • 29 By TLC, we detected a second more polar product spot. This observation fuels our speculation that the mediocre yield results from the undesired cleavage of the PMB ether and the PMP acetal.
  • 30 Attempted MnO2 oxidation led to no conversion.
