A Mechanistic Dehydration Study with [2-13C]-DIMBOA
摘要:
Dehydration of a 2-C-13-labeled synthetic sample of the natural aglucone 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one ([2-C-13]-DIMBOA, 10) using N-ethoxycarbonyltrichloroacetaldimine led to 3-formyl-6-methoxybenzoxazolin-2(3H)-one (C-13-labeled FMBOA, 11) with complete transfer of the C-13 label into the -CHO group. On the basis of this finding, a mechanism for the dehydration is proposed.
