Design and Synthesis of a Conformationally Restricted Cysteine Protease Inhibitor

Using the X-ray analyses of papain and papain-chloromethyl ketone inhibitor complexes as representative cysteine protease structures, molecular graphics analyses were applied to design (4R,1'S)-2-ethyl>-4-benzyl-4-(2-oxoeth

Enol esters as intermediates for the facile conversion of amino acids into amides and dipeptides

N-Protected amino enol esters are easily transformed at room temperature into amino amides, and in the presence of potassium cyanide as catalyst, into tertiary amides and dipeptides.

Investigation of New Chiral 1,3-Oxazolidine-2-thiones: Analytical Separation and Optical Resolution of Racemic Carboxylic Acids and Amino Acids

New chiral five-memebered heterocycles, (4S)-(4) and (4R)-4-ethyl-1,3-oxazolidine-2-thione (5), (4S)-4-isopropyl-1,3-oxazolidine-2-thione (6), and (4R,5S)-4-methyl-5-phenyl-1,3-oxazolidine-2-thione (7) have been developed.Among these heterocycles, (4R,5S)-MPOT (7) proved to be an excellent chiral reagent for analytical and efficient separation of racemic products from transformations of chiral carboxylic acids and amino acids.
