Hept-6-en-1-yl Furan-2-carboxylate

This study aims to develop an efficient and green one-pot method for the synthesis of 6-en-1-yl furan-2-carboxylic acid heptyl ester. Initially, using furfural as the starting substrate, hept-6-en-1-yl furan-2-carboxylate was prepared using a one-pot method. This study developed a new experimental scheme for preparing ester compounds, using cuprous chloride as a catalyst and tert butyl hydrogen peroxide as an oxidant to prepare furoic acid. Without the need for intermediate treatment, the target product can be directly obtained from furfural by adding 7-bromo-1-heptene, TBAB, and potassium carbonate. This method effectively utilizes furfural as a platform chemical, demonstrating its potential for synthesizing high-value chemicals. The entire synthesis process is simple and efficient, following the principles of green chemistry.
