Orthoamides, IX: Reaction of CH-Acidic Compounds with Amide Acetals, an Aminal-tert-butylester and Tris(dimethylamino)methaneOrthoamides react with hydrogen cyanide and alkynes to give 2-dimethylamino-2-alkoxy-nitriles (2, 4, 6, 8, 10), 2,2-bis(dimethylamino)nitriles (12,12a), and 3,3-bis(dimethylamino)-alkynes (14-16). Methane derivatives heated with dimethylformamide diäthylacetal (1) react to form the alkylated methane derivatives (25, 26, 28, 29, 30, 34), whereas under mild conditions methane derivatives react with the aminal tert-butylester 11 to produce tetramethyl-formamidinium salts (31, 32, 33, 35).
Notes:
Orthoamide reagieren mit wasserfreier Blausäure und Alkinen zu 2-Dimethylamino-2-alkoxy-nitrilen (2, 4, 6, 8, 10), 2.2-Bis-dimethylamino-nitrilen (12, 12a) und 3.3-Bis-dimethylamino-alkinen-(l) (14-16). Aus Methan-Derivaten und Dimethylformamid-diäthylacetal (1) ent-stehen in der Wärme die alkylierten Methan-Derivate (25, 26, 28, 29, 30, 34) und mit dem Aminal-tert.-butylester 11 unter milden Reaktionsbedingungen die Tetramethylformamidini-um-Salze(31,32, 33,35).
