1-Boc-Pyrrolidine - Introduction
tert-butyl 1-Pyrrolidinecarboxylate (tert-butyl 1-Pyrrolidinecarboxylate) is an organic compound whose chemical formula is C10H19NO2.
Nature:
tert-butyl 1-pyrrolidinecarboxylate is a colorless liquid with a special fragrance. It has a density of about 0.91g/cm³ and a boiling point of 150-152°C.
Use:
tert-butyl 1-Pyrrolidinecarboxylate is commonly used as a protecting group in organic synthesis. It can react with the functional group of the target compound to undergo an esterification reaction, and form a reversible protecting group to protect the target functional group from interference from other reactions. If desired, the protecting group can be removed by the corresponding acid or base, restoring the original functional group of the target compound.
Preparation Method:
tert-butyl 1-pyrrolidinecarboxylate can be prepared by the following steps: First, tetrahydropyrrole is reacted with tert-butyl bromoacetate under alkaline conditions to generate the target product tert-butyl 1-pyrrolidinecarboxylate. After completion of the reaction, a pure product can be obtained by acid treatment.
Safety Information:
tert-butyl 1-Pyrrolidinecarboxylate is a stable compound under normal conditions, there may be a risk of explosion and fire when exposed to high temperatures, open flames or high energy conditions. It is a flammable liquid and should be kept away from sources of fire and high heat. At the same time, use should wear appropriate protective equipment, avoid skin contact and inhalation.
