R. Rodriguez et al., CONFORMATIONALLY RESTRICTED ANALOGS OF TRYPTOPHAN - SYNTHESIS OF CHIRAL 3-AMINO-4-INDOLYL-2-PIPERIDONES, Synthetic communications, 26(16), 1996, pp. 3029-3059
The {Trp-phenylglycinol} pseudodipeptide (alpha toxy-1-phenylethyl)-3-
amino-4-indolyl-2-piperidone 33 has been synthezised by condensation o
f the 3-amino-substituted anhydride 30 with (R)-(-)-phenylglycinol fol
lowed by reduction of the resulting imide.
