Benzoate Group Migration in Mitsunobu Reaction of N3-benzoyl-5-fluorouracil with Benzoic acid, 2-chloro-5-hydroxy-bicyclo<2.2.1>hept-7-ylmethyl Ester

Abstract:

By Mitsunobu reaction of N3-benzoyl 5-fluorouracil with 2-chloro-5-hydroxy-bicyclo[2.2.1]hept-7-ylmethyl benzoate no nucleoside was obtained. Instead nucleoside we observed a benzoate group migration with the formation of bis-benzoylated compound (5). The structure of this compound was proved by MS, IR, 1H- and 13C-NMR (with complementary COSY and HETCOR spectra), and also by synthesis of the compound by benzoylation of the starting intermediate (1).
Keywords:
Mitsunobu synthesis; N3-benzoyl 5-fluorouracil; 2-chloro-5-hydroxy-bicyclo<2.2.1>hept-7-ylmethyl benzoate; bicyclo<2.2.1> heptane; benzoate group migration
