摘要:
Use of alkyl substituted propylene linkers as a strategy for fine-tuning the biological activity of medicinal agents requires ready access to these substrates. Herein, a general strategy is described for stereo specifically generating 18 chiral mono- and di-methylpropylene linkers. All twelve vicinal 1,2-propylene targets were generated from methyl-3-hydroxybutanoate and all 1,3-disubstituted targets from pentane-2,4-diol. (c) 2006 Elsevier Ltd. All rights reserved.
