The Preparation of 2-Hydroxyethyl-2,3-dihydro-2h-1,4-benzoxazin-3(4h)-one Derivatives
摘要:
An efficient synthesis of 2-hydroxyethyl-2,3-dihydro-2H-1,4-benzoxazin-3(4H)one derivatives is described using alpha-bromo-gamma-butyrolactone as a bis-electrophile containing a latent hydroxyethyl functional group.
