The diamine 1,4-bis(4-aminophenoxy)-2,5-di-tert-butylbenzene, containing symmetric, bulky di-tert-butyl substituents and a flexible ether unit, was synthesized and used to prepare a series of polyamides by the direct polycondensation with various aromatic dicarboxylic acids in N-methyl-2-pyrrolidino
Pyroglutamic acid derivative (I) is proved to be an excellent chiral starting compound for the synthesis of title amino acids (IX), (X), and (V). The syntheses are based on a combination of methods previously used for the preparation of 4-and 5-substituted prolines. These methods are the ring openin
