Synthesis and anticonvulsant activity of some substituted lactams and amides
Abstract:
Thirteen derivatives of 3-phenyl-2-piperidinone were synthesized and evaluated for anticonvulsant activity. The most active compounds from this group included two simple lactams, 3-hydroxy-1-methyl-3-phenyl-2-piperidinone and 3-methoxy-3-phenyl-2-piperidinone, and two N-ethoxycarbonyl lactams, 1-(ethoxycarbonyl)-3-hydroxy-3-phenyl-2-piperidinone and 1-(ethoxycarbonyl)-3-methoxy-3-phenyl-2-piperidinone, whose anticonvulsant activity was comparable to or better than that for valproic acid. Four related acyclic amides were also prepared, but these were essentially inactive as anticonvulsants.

Acid Halides to Amides: Aminolysis
In the first step of the aminolysis mechanism, the amine attacks the carbonyl carbon of the acyl chloride to form a tetrahedral intermediate. In the second step, the carbonyl group is re-formed with the elimination of a chloride...
Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
