A High-Yield Selective N(3)-Alkylation Process of Hydantoins Using Dimethylformanide Dialkyl Acetals
摘要:
AbstractA selective N(3)‐alkylation process of 5‐substituted hydantoins is described. Treatment of hydantoins with excess of dimethylformamide dialkyl acetals at 100°C results in N(3)‐alkyl derivatives in 69–90% yield.
