| Abstract: | Reactions of 9-(2,2-dichlorocyclopropyl)carbazole, 10-(2,2-dichlorocyclopropyl)phenothiazine, and 10-(2,2-dichlorocyclopropyl)phenoxazine with alcohols in the system t-BuOK-DMSO yield the corresponding N-(1-alkoxy-2-propynyl) derivatives. Hydrolysis of 9-(1-methoxy-2-propynyl)carbazole and 10-(1-methoxy-2-propynyl)phenothiazine in 60% aqueous dioxane in the presence of sulfuric acid gives the corresponding heterocyclic amine and 2-propynal. |
