The enantioselective totalsynthesis of candidate structures for communiols E and F, novel bicyclic polyketides of fungal origin, was accomplished using a Lewis acid-mediated ring closure reaction of an allylsilane intermediate as the key step. Comparison of the spectral data of the synthetic materials with those of natural communiols E and F, coupled with biosynthetic considerations, led to the conclusion

Enantioselective synthesis of 5-substituted pipecolic acids using an intramolecular allylsilane-iminium ion cyclization
The application of the intramolecular allylsilane-iminium ion cyclization reaction for the enantioselective synthesis of piperidine derivatives is described. The synthetic potential of this methodology is demonstrated by the enantioselective synthesis of 5-substituted pipecolic acids. (C) 2000 Elsevier Science Ltd. All rights reserved.
