Conformationally Restricted Analogues of Tryptophan: Synthesis of Chiral 3-Amino-4-indolyl-2-piperidones
摘要:
The {Trp-phenylglycinol} pseudodipeptide (alpha R,3R*,4R*)-N-(2-acetoxy-1-phenylethyl)-3-amino-4-indolyl-2-piperidone 33 has been synthezised by condensation of the 3-amino-substituted anhydride 30 with (R)-(-)-phenylglycinol followed by reduction of the resulting imide.

A series of 2-(indol-3-yl)-1-nitroethenes containing an ester, acetyl, benzoyl, or cyano group in the geminal position with respect to the nitro group have been synthesized, and their structure has been studied by 1H, 13C−1H} NMR, IR, and UV spectroscopy.
