چکیده

Multicomponent reactions are performed without need to isolate any intermediate during the reaction, which reduce the amount of time and energy used [1]. There has been tremendous development in three or four component reactions. 1amidoalkyl2naphthol derivatives have been attracted considerable interest because of their biological and pharmacological activities [2,3]. In this work, a new strategy has been introduced for the preparation of 1amidoalkyl2 naphtoles. In this regards, glycerosulfonic acid has been synthesized and new applications of this catalyst explored. Therefore a variety of 1amidoalkyl2naphtoles have been prepared via combination of aromatic aldehydes, acetamide and 2naphtol in the presence of a catalytic amounts glycerosulfonic acid at 80 0C
