TRANSFORMATION OF DIHYDRO-1,5-BENZODIAZEPIN-2-ONES UNDER THE INFLUENCE OF ACETIC ANHYDRIDE
Puodzhyunaite, B. A.,Yanchene, R. A.,Terent'ev, P. B.
, p. 311 - 317 (2007/10/02)
The acylation of 4-R-2,3-dihydro-1H-1,5-benzodiazepin-2-ones leads to isomerization or opening of the heteroring with subsequent acylation. 1-Acyl-2,3-dihydro-1,5-benzodiazepin-2-ones are not formed.
