Diphenylmethyl Protective Group in the Synthesis of 5-Substituted 3-Nitro-1H-1,2,4-triazoles
摘要:
A diphenylmethyl protective group is suggested for use in the synthesis of 5-R-3-nitro-1H-1,2,4-triazoles unsubstituted at the cyclic nitrogen atom, via nucleophilic substitution of 5-bromo- and 5-methylsulfonyl groups.
