  Synthesis of a Potential Key Intermediate of Akaterpin, Specific Inhibitor of PI-PLC

  摘要：

  In order to establish the stereochemistry of akaterpin, a specific inhibitor of PI-PLC, cis-decalin 2 and tuans-decalin 3 were prepared. Comparison of NMR spectra of 2 and 3 with those of akaterpin indicated that the upper decalin has a cis-fused structure. Based on the methodology developed here, synthesis of a potential intermediate 32 for the total synthesis of akaterpin was successfully achieved. Further, resolution of beta,gamma-unsaturated ketone 6 was accomplished using chiral sulfoxyimine. (C) 2000 Elsevier Science Ltd. All rights reserved.

  In order to establish the stereochemistry of akaterpin, a specific inhibitor of PI-PLC, synthesis of cis-decalin 2 and trans-decalin 3 was carried out. Comparison of NMR spectra of 2 and 3 with that of akaterpin indicated that the upper decalin has a cis-fused structure. (C) 1999 Elsevier Science Ltd. All rights reserved.
