A general access to 3-hydroxy-4-(1-hydroxyalkyl)-b-lactams with a C 4 -C 1 % relative configuration unlike is provided. The subsequent oxidative ring expansion of the corresponding 3-hydroxy b-lactam smoothly affords an a-amino acid N-carboxy anhydride (NCA) formally derived from (2S,3S)-b-substitut
## Abstract magnified image A novel and facile oneβpot procedure for the preparation of 2,4βdiaminoβ6βsubstitutedβsβtriazine derivatives (IIaβn) was reported. The scope of its application was demonstrated with a number of examples. The new procedure involved treatment of proguanil or chloroproguan
