Abstract: | The higher molecular ketones, undecanone-6 (1), tridecanone-7 (2), pentadecanone-8 (3), heptadecanone-9 (4) react with ethylenimine and sulfur to give 2,3-disubstituted 5,6-dihydro-1,4-thiazines (9–12) and 2,2-dialkylated thiazolidines (17–20). The reduction of9–12 with formic acid yields the corresponding thiomorpholines13–16 (70–90% yield).9–12 is also obtained by the reaction of -chloro ketones (5–8) and the sodium salt of cysteamine 30–75% yield); cysteamine reacts with1–4 to give the thiazolidines17–20 (37–53% yield).Teil der DissertationJ.
