A process for the preparation of acyl phosphate esters of the formula I or salts thereof: ##STR1## wherein R and R.sup.1 are the same or different and represent a linear or branched alkyl group having up to 4 carbon atoms, phenyl or benzyl; n is an integer; when n is 1, R.sup.2 represents the group ##STR2## wherein R.sup.4 is a linear or branched alkyl, alkenyl or alkynyl, a cyclic alkyl, a cyclic alkenyl, or aryl which may be substituted by alkyl, alkenyl, alkynyl, aryl, arylalkyl, or arylalkenyl, or when n is at least 2, R.sup.2 represents the group ##STR3## wherein R.sup.4 is as defined above. Novel compounds of the formula I wherein n is at least 2, and modified hemoglobin obtained using the novel compounds are also provided.
一种制备公式I或其盐的酰基磷酸酯的方法:其中R和R.sup.1相同或不同,表示具有最多4个碳原子的直链或支链烷基,苯基或苄基;n是整数;当n为1时,R.sup.2表示基团##STR2##其中R.sup.4是直链或支链烷基,烯基或炔基,环烷基,环烯基或芳基,可能被烷基,烯基,炔基,芳基,芳基烷基或芳基烯基取代,或当n至少为2时,R.sup.2表示基团##STR3##其中R.sup.4如上所定义。还提供了n至少为2的公式I的新化合物以及使用这些新化合物获得的改性血红蛋白。
