Paragraph 0043-0046, (2019/06/30)
The invention belongs to the technical field of organic synthesis, and particularly relates to a preparation method for cinnamaldehyde and derivatives thereof. The preparation method includes taking styrene or derivatives thereof as a substrate, reacting the substrate with a formamide solvent, iodoform and alkali at a certain temperature and under the protection of argon, and completing carbonylation to generate target products, namely the cinnamaldehyde and the derivatives thereof. The preparation method of the cinnamaldehyde and the derivatives thereof has the advantages of low cost and easyavailability of raw materials, no metal catalysis, environmental friendliness, high reaction yield and the like, thereby having a good industrial application prospect.

A metal-free Bronsted acid promoted two-component reaction between cinnamaldehydes and sulfonamides is described. This cascade process provides a simple and atom-economical alternative synthesis of a range of functionalized indenes from easily available starting materials. The resulting N -indenylsulfonamides were readily converted into the corresponding indenylenamines or indanones.
