ZSM-5-SO3H: An Efficient Catalyst for Acylation of Sulfonamides Amines, Alcohols, and Phenols under Solvent-Free Conditions
Sulfonamides amines, alcohols, and phenols were efficiently acylated with carboxylic acid anhydrides and chlorides using ZSM-5-SO3H as catalyst under mild and solvent-free conditions. Also, direct esterification of alcohols with carboxylic acids occurred readily in the presence of this catalyst. Different types of amides and esters were obtained in moderate to high yields and purity after a sim...
متن کاملDiastereoselective Three-Component Synthesis of β-Amino Carbonyl Compounds Using Diazo Compounds, Boranes, and Acyl Imines under Catalyst-Free Conditions
Diazo compounds, boranes, and acyl imines undergo a three-component Mannich condensation reaction under catalyst-free conditions to give the anti β-amino carbonyl compounds in high diastereoselectivity. The reaction tolerates a variety of functional groups, and an asymmetric variant was achieved using the (-)-phenylmenthol as chiral auxiliary in good yield and selectivity. These β-amino carbony...
متن کاملA Highly Efficient Protocol for the Synthesis of 2-Amidoalkylphenols using SO3H-Functionalized Phthalimide (SFP) under Solvent-free Conditions
A highly efficient and simple protocol for the synthesis of 2-amidoalkylphenols has been described. The one-pot multi-component condensation of phenols with aromatic aldehydes and amides in the presence of catalytic amount of SO3H-functionalized phthalimide (SFP) under solvent-free conditions afford the title compounds in high yields and relatively short reaction times. It is noteworthy that th...
