Gupta, Sharad published the artcileSynthesis of structurally diverse bis-peptide oligomers, Category: alcohols-buliding-blocks, the publication is Journal of Organic Chemistry (2006), 71(23), 8691-8695, database is CAplus and MEDLINE.
The authors have developed second-generation monomers I (n = 1, 2) and improved conditions for rapidly and simultaneously closing multiple diketopiperazines on solid support. These new conditions involve either the microwave heating of a suspension of solid-supported amino-tetrafluoropropyl esters in acetic acid/triethylamine catalyst solution or continuous flow of catalyst solution through the resin, heated in a flow cell apparatus The authors demonstrate that monomers I and II can be combined with the new conditions easily to synthesize previously inaccessible hetero and homo spiro ladder oligomers III and IV.
