Regioselective Addition of Grignard Reagents to New Lipophilic Isoquinolinium Salts Applied to the Synthesis of Stable Ethyl 1,2-disubstituted 1,2-Dihydroisoquinoline-3-carboxylates and Derivatives

Meziane, Mohamed Ait Amer,Bazureau, Jean Pierre

, p. 1703 - 1706 (2001)

New and stable ethyl 1,2-disubstituted 1,2-dihydroisoquinoline-3-carboxylates 6 and 12a were synthesized in good yields by regioselective addition reactions of alkyl Grignard reagents to lipophilic and soluble isoquinolinium salts 4 and 11. The salts 4 an
