The synthesis of MeLeu and MeLeu-D-Leu alkene dipeptideisosteres are described. Isosteres with an E-alkene bond were synthesized stereoselectively by employing the [2, 3] Wittig rearrangement to control double bond geometry and C-2 configuration. Z-alkene isosters were obtained as an easily separable mixture of diastereomers via alkylation of a Z-alkene MeLeu-Gly isostere that was obtained using a
