Synthesis of the hydroxyethylene isostere of Leu-Val
摘要:
The hydroxyethylene isostere of the dipeptide leu-val was synthesized from isovaleryl aldehyde in nine steps in 15% overall yield without the use of chromatographic separations. A key finding is the ability of an amide to selectively direct an epoxidation in an acyclic system and that the selectivity is a function of the amide's size.
