• Process for preparing monoesters
  申请人：Wicki A. Markus

  公开号：US20050143599A1

  公开（公告）日：2005-06-30

  A process for preparing monoesters comprises the step of reacting at least one diol with at least one carboxylic acid in a biphasic solvent system, the carboxylic acid being sufficiently water soluble to allow esterification to occur, and the biphasic solvent system comprising water and at least one aprotic solvent in which the resulting monoester has greater solubility than in water.

  制备单酯的过程包括在两相溶剂系统中，将至少一种二醇与至少一种羧酸反应的步骤，其中羧酸足够水溶性以允许发生酯化反应，而两相溶剂系统包括水和至少一种无质子溶剂，其中得到的单酯比水具有更大的溶解度。

  Structure (XXIII) is suggested for ostreogrycin A, an antibiotic produced by the soil organism Streptomyces ostreogriseus. Acid hydrolysis of “perhydro A,” prepared by complete hydrogenation of the antibiotic, yields inter alia 4,6-dimethyl-γ-heptanolactone, DL-alanine, proline, and 10-amino-7-methyl-δ-dec-2-enolactone. Ozonolysis of the antibiotic with oxidative working-up yields glycine and β-alanine

  对于土壤生物链霉菌链霉菌（Streptomyces ostreogriseus）生产的抗生素，建议使用ostreogrycin A的结构（XXIII）。通过对抗生素进行完全加氢制备的“过氢A”经过酸水解，除其他外，可产生4,6-二甲基-γ-庚内酯，DL-丙氨酸，脯氨酸和10-氨基-7-甲基-δ-dec-2-内酯。具有氧化作用的臭氧臭氧分解产生甘氨酸和β-丙氨酸，而还原性臭氧分解产生甲基乙二醛和2,4-二甲基戊-2-烯醛。抗生素中恶唑环系统的存在可解释由于原丝球蛋白A及其还原产物的水解而产生少量甘氨酸和丝氨酸。
