A method of making an amino acid triisocyanate is provided, the method comprising reacting an amino acid trihydrochloride with phosgene to form the amino acid triisocyanate. In some embodiments, the amino acid trihydrochloride comprises lysine ester trihydrochloride salt and the amino acid triisocyanate comprises lysine ester triisocyanate. In some embodiments, there is a lysine ester triisocyanate having a purity of at least about 98%, the lysine ester triisocyanate having a structure resulting from reacting lysine ester trihydrochloride salt with phosgene to form the lysine ester triisocyanate. These lysine ester triisocyanates can be used to make biodegradable polyurethanes.

diastereoselective samarium diiodide and D(2)O-promoted conjugate reduction of homochiral (E)- and (Z)-benzylidene and isobutylidene diketopiperazines (E)-5,7 and (Z)-6,8 has been demonstrated. This methodology allows the asymmetricsynthesis of methyl (2S,3R)-dideuteriophenylalanine 27 in > or = 95% de and >98% ee, and (2S,3R)- or (2S,3S)-dideuterioleucine-(S)-phenylalanine dipeptides 37 and 38 in moderate de,

In some embodiments, a method of making an amino acid trihydrochloride is provided, the method comprising reacting an amino acid monohydrochloride with an alkanolamine to form the amino acid trihydrochloride. In some embodiments, the amino acid monohydrochloride comprises lysine hydrochloride, which is mixed with ethanolamine to form lysine ester trihydrochloride. In some embodiments, there is a lysine ester trihydrochloride salt having a purity of at least about 98%, the lysine ester trihydrochloride salt having a structure resulting from reacting lysine hydrochloride and ethanolamine to form the lysine ester trihydrochloride salt. The lysine ester trihydrochloride can be made in one reaction vessel.
