RING OPENING AND CLOSING REACTIONS OF IMIDAZOLES AND OTHER 1,3-DIAZAHETEROCYCLES WITH VINYL CHLOROFORMATE AND PHENYL CHLOROFORMATE

Pratt, R. F.,Kraus, K. K.

, p. 2431 - 2434 (2007/10/02)

Treatment of imidazole and benzimidazole with vinyl chloroformate or phenyl chloroformate in weakly alkaline aqueous solution leads to their conversion into the corresponding imidazol-2-ones; in weakly acidic solutions these chloroformates convert adenine into isoquanine, 6-methylaminopurine into 1-methylisoquanine and pyrimidine into an acyclic product.
