    摘要: The present invention has for its object to provide an efficient and economical method for producing an 3-amino-2-hydroxy-1-propanol derivative and an oxazolidinone derivative derived therefrom, both of which are of use as intermediates for the production of drugs including HIV protease inhibitors. The invention relates to a method for producing an 3-amino-2-hydroxy-1-propanol derivative of general formula (2) ##STR1## (wherein R.sup.1 represents alkyl, aralkyl or aryl; R.sup.2 and R.sup.3 independently represent hydrogen or an amino-protecting group, provided, however, that both R.sup.2 and R.sup.3 are not concurrently hydrogen) and an oxazolidinone derivative derived therefrom.
