It was reported in our previous papers (1) that, on heating at 2oo0, ally1 bquinolyl ethers were readily converted into the Claisen products, 3-allyl-4(1H)quinolones, in good yields accompanying small amounts of ring closure products, P,%dihydrofuro-[ 32-cjquinolines.

Earlier, we reported that the thio-Cloisen reorrongement of ally1 4quinolyl sulfides (I) to 2,3-dihydrothieno[3.2-clquinolines (III) proceeded through the prototropic cyclizotion of the initially formed 3-allyl-4(1 H)-quinolinethiones (II), on the basis of the quantitative transformation of II into
