Reactions of 2-Polyfluoroalkylchromones with Aliphatic Diamines. -The reaction of aliphatic 1,2-diamines with the title chromones affords 2,3-dihydro-1H-1,4-diazepines [cf. (III), (VI)/(VII)] in good to excellent yields. A similar reaction with 1,3-diaminopropane leads to trimethylenebis(hydroxya

โฆ Synopsis
Acylation of Aliphatic Diamines with Methyl Nitroacetate.
-The first synthesis of N,N'-bis(nitroacetyl)diamines (cf. (IV), (VI)) by acylation of the corresponding diamines with nitroacetate (II) is accomplished. The reaction proceeds via isolable zwitterionic N-mononitroacetyl derivatives (cf. (III)). -(LYAPKALO, I.
