A facile synthesis and some new reactions of N-benzylcarboxamides with essential amino acids
El-Sayed, Ragab A.
, p. 1059 - 1062 (2007/10/03)
N-Benzyl-p-chloro and N-benzyl-2,4-dichlorobenzamide react with chlorosulfonic acid to give the corresponding p-sulfonyl chlorides 1, 19, which on condensation with nucleophiles give amino acid derivatives 2-7 and 20-25. Some of the corresponding methyl e
