The samarium(II) iodide mediated reaction of N,N-dibenzyl-protected (S)-α-amino aldehydes with (1S,2R)-N-methylephedrinyl acrylate gave the (4R, 1′S)-γ-(aminoalkyl)-γ-butyrolactones in good yields with high diastereoselectivities (up to 80% de); (4R, 1′S)γ-amino-(2-phenylethyl)-γ-butyrolactone (6a), which should be a potent precursor for γ-secretase inhibitors, was obtained with high de value.
