Cyclic tautomers of tryptophan: Enantio- and diastereoselective synthesis of β-substituted and α,β-disubstituted derivatives of tryptophan

A method is presented for the synthesis of enantiomerically pure erythro-β-alkylated derivatives of L-tryptophan from L-tryptophan itself via the intermediacy of cyclic tryptophan tautomers. Dehydrogenation of the cyclic tryptophan tautomer 2 to 3 is achi

Conformationally restricted amino acids: Diastereoselective substitution at the β-position of L-tryptophan

Higher order cuprates add with extreme exo-facial selectivity to the chiral tetrahydropyrroloindole 3, itself prepared in enantiomerically pure form from L-tryptophan: treatment of the adducts with trifluoroacetic acid provides diastereo- and enantiomeric
