QUINOLINES WITH HETEROATOM SUBSTITUENTS IN POSITION 2 AND 4
Khattab, A.,Zeid, I.,Kappe, T.
, p. 521 - 528 (2007/10/02)
Thio ethers 2a-d and 4a-d are prepared by nucleophilic substitution of 2,4-dichloro-3-phenylquinoline 1 with thiolate anions.Acid hydrolysis of 2a-d afforded the corresponding 2-quinolinones 3a-d, while, on acid hydrolysis of 4a-d, only 4a is converted to
