substituted (4S)-4-(hydroxymethyl)imidazolidin-2-ones from D-serine methyl ester is described. The key step in the synthesis is a reductive amination reaction which is brought about usingtitanium(IV) isopropoxide and sodiumcyanoborohydride, followed by the cyclization to urea using triphosgene after deprotection.
