Bildung und virushemmende Wirksamkeit von N‐[Adamantyl‐(1)]‐thioharnstoffen

Abstract: 30s 1 72 N-[A&manfyl-(I) 1-thiohamstoffe 907 (7a) 19,6 g (0,l Mol) Kaliumsalz 1 in 75 ml Athano1 werden unter Riihren mit einer athanol. Losung von 25.4 g (0.1 Mol) Jod versetzt. Dabei scheiden sich 27.6 g (97% d. Th.) eines hellbraunen Sakes ab, das wegen mangelnder Liislichkeit nicht weiter gereinigt werden konnte. Sein IR-Spektrum entspricht dem des Perchlorats 7b. IR(KBr): 3,lO und 3,35 p (uNH2); 4,45 p ( e N ) ; 6,14 p (6NH2); 6,67 p. -5-methyl-4cyan-I,2-dithiolium-perchlorat (7b) 15,8 g (0,l Mol) reines … Show more
