Polycondensations of dicarboxylic acids with diols having amide moieties derived from optically active amino alcohols were carried out. Polymers with M V n s 8,700- 17,400 were obtained by the polycondensations using 1.2 eq. of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDCrHCl) i

Simple amino acids (1) can be converted in fair to good yield into hydrazino acids (3) of like configuration by using KOCI instead of NaOCl to promote the Shestakov rearrangement of the intermediate hydantoic acids (2). It was shown fifteen years ago by Karady et al.,' and later by Custafsson,' that
Two optically active cationic surfactants, (2S)-N-hexadecyl-N, N-dimethyl-(1-hydroxy-3-phenylpropyl)-2-ammonium chloride 1 and (2S)-N-hexadecyl-N,N-dimethyl-(1-hydroxy-4-methylpentyl)-2-ammonium chloride 2, have been selected and synthesized for use as enantioselective micellar catalysts in aqueous
The synthesis of three new stereoregular AB-type polyamides based on Dribono-1,4-lactone, L-arabinose, and D-xylose has been carried out by the active ester polycondensation method. These polyamides were characterized by elemental analysis, IR and NMR spectroscopies, and powder X-ray diffraction. Th
