2,3-O-(1-Methylethylidene)- - Introduction

4-lactone is an organic compound with the chemical formula C8H12O5. Its molecular structure contains a lyxonic acid ring, and carbon atoms 2 and 3 are connected with an isopropylidene group.

2,, 4-lactone is often used in organic synthesis as an important synthesis intermediate. It can be used in the synthesis of various natural products and drugs. For example, it can be used for the synthesis of heparin drugs and plant secondary metabolites.

The method for preparing 2, 4-lactone is generally obtained by reacting lyxonic acid (lyxonic acid) with ethyleneacetone (acetone).

When using 2, and 4-lactone, pay attention to some safety information. This compound may be irritating to the skin, eyes and respiratory tract, so it is necessary to take appropriate protective measures when handling, such as wearing protective glasses, gloves and breathing masks. In addition, inhalation of its dust and contact with food or drinking water should be avoided. In case of accidental contact, rinse immediately with plenty of water and seek medical help.
