Zusammenfassung: | The title amides are of formula (I): (where R1 is a (4-10)C aliphatic residue opt. interrupted by O or S and/or carrying an OH gp, any gp or heteroatom being sepd. from CONH by >=2C: R2 is H or 1-3C aliphatic residue opt. substd. by phosphinyl opt. carrying alkyl, hydroxylakyl and/or alkoxy-alkyl (each alkyl or alkoxy contg. 1-3C); n is 3-5 and X is OH or H) are prepd. by reacting an alclonic acid lactone or ester with R1R2NH. The d (+)-gluconic acid 2-(+)-heptylamide is prepd. from (+)-2-amino heptane and d (+)-gluconic acid. |
