Alkylation-Terminated Catellani Reactions Using Alkyl Carbagermatranes

The Catellani reaction has received substantial attention because it enables rapid multiple derivatization on aromatics. While using alkyl electrophiles to achieve ortho-alkylation was one of the earliest applications of the Catellani reaction, ipso-alkyl

Synthesis of novel 3,4-dihydroquinolin-2(1H)-one guanidines as potential antihypertensive agents

Hydroxy-3,4-dihydroquinolin-2(1H)-ones (4a-c) were synthesized by intramolecular Friedel Craft alkylation of N-(methoxyphenyl)-3- chloropropionamides (3a-c), obtained by acylation of anisidine with chloropropionyl chloride. The hydroxy-3,4-dihydro quinolin-2(1H)- ones (4a-c) were treated with various dibromo alkanes under phase transfer catalyst conditions at room temperature to give bromoalkyloxy- 3,4-dihydroquinolin-2(1H)- ones (5a-l) which on further reaction with guanidine hydrochloride in dimethyl formamide afforded N-{4- [(2-oxo-1,2,3,4-tetrahydroquinolin-5-yl)oxy]alkyl} guanidines (6a-l). These compounds were synthesized as potential antihypertensive agents.
