Abstract
A diastereoselective synthesis of the unnatural (+)-enantiomer of the hexahydropyrroloindole alkaloid (-)-pseudophrynaminol (3), isolated fr om the skin of the Australian frog Pseudophryne coriacea, from a cycli c tautomer (1) of L-tryptophan, is described, The CD spectrum of the s ynthetic 3 is opposite in sign to that of the natural material enablin g the configuration of the natural product to be established as 3aS,8a R.
