En. Prabhakaran et al., Synthesis of cyclic peptides as mimics for the constrained conformation ofstructural analogues of HIV protease inhibitors, TETRAHEDR L, 42(2), 2001, pp. 339-342
A gamma -turn induced cyclisation of tripeptides 4 can be performed in a ri
ng-closing metathesis reaction using Grubb's catalyst to the corresponding
cyclic peptides 5. These cyclic peptides mimic the constrained conformation
of structural analogues of potential HIV protease inhibitors. (C) 2000 Els
