Abstract
The four-membered spiro-heterocycles; ethyl cyano(1-methyl-2,4-dioxospiro{1,3-quinoline-3,4'-[1,3]dithietane}-4'-ylidene)- acetate 2a, -malononitrile 2b, -acetylacetone 2c and thiazetidine isomer 3 were prepared under phase transfer catalysis conditions (PTC). The thermal treatment of dithietanes 2a–c led to the bis-quinolinyl sulfide 4. Some interesting nucleophilic addition followed by cyclization reactions were carried out with the dithietane 2a to give the corresponding novel dispiro derivatives 5–8, 10–13, and 15.
