1,3-dioxolen-2-one derivative, 4-bromomethyl-5-methyl-1,3-dioxolen-2-one, and a process for the production thereof

摘要

The invention describes 4-broimomethyl-5-methyl-1, 3-dioxolen-2-one which is useful as a protective group-introducing agent for introducing protective groups into reagents in various chemical reactions, or as a modifier for prodrug preparation in medicine. The above compound can be prepared by reacting 1.0 mole of 4, 5-dimethyl-1, 3-dioxolen-2-one with 0.87-1.19 mole of N-bromosuccinimide or N-bromophthalimide.
