Introduction
It is a colorless liquid with a special amino group and a cyclic structure. There are various methods for preparing (R)-3-Aminotetrahydrofuran. A common method is to use an enantioselective enzyme as a catalyst for enzymatic resolution to separate (R)-3-Aminotetrahydrofuran from a mixture. It can also be obtained through chemical methods, such as performing a reduction reaction in the presence of cycloheptanone to get the target product. It is an irritant, and contact with skin or eyes may cause irritation. Additionally, it has certain toxicity to the environment and should be prevented from causing environmental contamination. During use, appropriate personal protective measures should be taken, such as wearing safety goggles, gloves, and a lab coat.
