Eine neue 1,3-Oxathiolan-Synthese: Spirocyclische 1,3-0xathiolane aus der Lewis-Säure katalysierten Umsetzung von 1,3-Thiazol-5(4H)-thionen mit Oxiranen


Tromm, Peter-Claus; Heimgartner, Heinz (1990). Eine neue 1,3-Oxathiolan-Synthese: Spirocyclische 1,3-0xathiolane aus der Lewis-Säure katalysierten Umsetzung von 1,3-Thiazol-5(4H)-thionen mit Oxiranen. Helvetica Chimica Acta, 73(8):2287-2294.

Abstract

The BF3.Et2O-catalyzed reaction of 2,4,4-trisubstituted 1,3-thiazole-5(4H)-thiones 13 with alkyl- and phenyl-substituted oxiranes 7 in CH2Cl2 at room temperature leads, in very good yields, to 1-oxa-4,6-dithia-8- azaspiro[4.4]non-7-enes 14 and 15.
