Allyltrichlorostannane additions to α-amino aldehydes: Application to the total synthesis of the aspartyl protease inhibitors L-682,679, L-684,414, L-685,434, and L-685,458

The hydroxyethylene dipeptide isosteres L-682,679, L-684,414, L-685,434, and L-685,458 were synthesized in a few steps by a sequence involving an allyltrichlorostannane coupling with an α-amino aldehyde, followed by hydroboration of the corresponding 1,2-

Short total synthesis of aspartyl protease inhibitors L-685,434, L-682,679 and L-685,458

Hydroxyethylene dipeptide isosteres L-685,434, L-682,679 and L-685,458 were synthesized in a few steps by a sequence involving an allyltrichlorostannane coupling with an α-aminoaldehyde followed by hydroboration of the corresponding 1,2-syn and 1,2-anti a

Asymmetric dihydroxylation route to a dipeptide isostere of a protease inhibitor: Enantioselective synthesis of the core unit of ritonavir

An enantioselective synthesis of the dipeptide isostere of ritonavir has been accomplished utilizing Sharpless asymmetric hydroxylation as the key step.

Peptide inhibitors of aspartic proteinases with hydroxyethylene isostere replacement of peptide bond. I. Preparation of four diastereoisomeric (2R or 2S, 4R or 4S, 5S)-2-benzyl-5-[(tert-butoxycarbonyl)amino]-4-hydroxy-6-phenylhexanoic acids

By two separate routes were prepared four diastereoisomers of (2R or 2S,5R or 5S)-3-benzyl-5-{(1S)-[(tert-butoxycarbonyl)amino]-2-phenylethyl}tetrahydrofuran- 2-ones (11, 12, 17 and 18). Since the furanones were derived from (S)-phenylalanine, absolute co
