Novel phosphorus-containing compounds and process for producing the same.

摘要

Disclosed are compounds having the following general formula:
<CHEM>
wherein n is an integer of 1 or 2; R<1> is an amino group when n is 2, or an amino group or a hydroxyl group when n is 1; and R<2> is a hydroxyl group when n is 1, or a hydroxyl group or a group of the formula
<CHEM>
when n is 2:
and microbiological process for producing the same.
The compounds are useful as precursors for raising the production rate of SF-1293 substance. Some of the compounds are also useful as intermediates for synthesis of 2-Amino-4-(hydroxy)(methyl)phosphinoylbutyric acid and the SF-1293 substance.
