I found the field of Chemistry very interesting. Saw the article Rapid and green synthesis of 4H-benzo[b]pyrans using triethanolamine as an efficient homogeneous catalyst under ambient conditions published in 2020.0. Product Details of 100-83-4, Reprint Addresses Moradi, L (corresponding author), Univ Kashan, Dept Organ Chem, Fac Chem, POB 8731753153, Kashan, Iran.. The CAS is 100-83-4. Through research, I have a further understanding and discovery of 3-Hydroxybenzaldehyde
4H-benzo[b]pyrans were obtained rapidly in high yields using triethanolamine as an efficient, eco-friendly and low-cost basic catalyst. One-pot three-component condensation reaction of a series of aldehydes, malononitrile and 1,3-diketones was performed at room temperature. All the products were obtained in high-to-excellent yields and characterized in detail. Green, rapid and mild process, very short reaction times (1-12 min) and simple workup are some of the advantages of this method.
