Skeletal Diversity by Ugi Four-Component Coupling Reaction and Post-Ugi Reactions
摘要:
Here we report a strategy to alter the skeletal complexity of Ugi four-component coupling reaction products by using allylations followed by ring-closing metathesis. Principal component analysis is also performed for these compounds.
Skeletal diversity by allylation/RCM on Ugi four-component coupling reaction products
摘要:
Here, we report a diversity-oriented synthetic approach toward skeletally diverse, cyclized peptidomimetics with diverse appendages. Starting from alpha-(N-acylamino)amides with various appendages, 12 to 16-membered lactams with defined olefin geometry were synthesized by a common synthetic sequence. We also synthesized the macrocycle in a liquid phase directed toward a construction of the peptidomimetics library. (c) 2006 Elsevier Ltd. All rights reserved.
