Synthesis of simplified halogenated chondramide derivatives with strong cytostatic properties
Becker, Dominic,Kazmaier, Uli
, p. 2591 - 2602 (2015/04/27)
Removing the methyl groups and the stereogenic centers from the ω-hydroxy acid of the chondramides results in a significant drop in the cytotoxicity of these interesting depsipeptides. This effect can be almost compensated for by introduction of a second
Chondramide C: Synthesis, configurational assignment, and structure-activity relationship studies
Eggert, Ulrike,Diestel, Randi,Sasse, Florenz,Jansen, Rolf,Kunze, Brigitte,Kalesse, Markus
scheme or table, p. 6478 - 6482 (2009/03/11)
(Chemical Equation Presented) Two solutions for one problem: Of the four isomers of chondramide C synthesized, the two shown in the scheme exhibit nearly the same conformation of the peptide segment and consequently unfold equal biological activities.
Self-Reproduction of Chirality. Asymmetric Synthesis of β-Aryl-β-amino Acids from Enantiomerically Pure Dihydropyrimidinones
Konopelski, Joseph P.,Chu, Kent S.,Negrete, George R.
, p. 1355 - 1357 (2007/10/02)
Enantiomerically pure dihydropyrimidinone 1 reacts with aryl iodides in the presence of catalytic amounts of Pd(OAc)2 and added phosphine to afford dihydropyrimidinone 4, in which a formal conjugate addition of the aryl group to the α,β-unsaturated system
