Synthesis of Carboalkoxychloro- and Bromodiazirines
摘要:
The first known 3H-diazirines bearing a carbonyl group and a halogen atom on C-3 have been prepared by a novel synthetic method. Carboalkoxychloro- and bromodiazirines 1a-d are formed in up to 45% yields by reductive dechlorination of carboalkoxy-N,N,N'-trichloroformamidines 9a,b using chloride or bromide ion. This method constitutes the first example of the use of N,N,N'-trichloroamidines as starting materials in organic synthesis.
