Abstract

A 1,3-dioxolen-2-one derivative of the general formula ##STR1## wherein R.sub.1 represents a hydrogen atom, a methyl group, or an aryl group, R.sub.2 represents a hydrogen atom, or may be taken together with R.sub.1 to form a divalent carbon chain residue, and x represents a halogen atom. The above compounds can be prepared by reacting a compound of the general formula ##STR2## with a halogenating agent, and are useful as protective group-introducing reagents for introducing protective groups into reagents in various chemical reactions, or as modifiers for prodrug preparation in medicine.
