Electric Literature of 541-16-2, The chemical industry reduces the impact on the environment during synthesis 541-16-2, name is Di-tert-Butyl malonate, I believe this compound will play a more active role in future production and life.
General procedure: alpha,beta-Unsaturated aldehyde (3.0 mmol) and malonate (3.0 mmol) were added into asolution of TiCl4 (6.0 mmol) in CCl4 (2.0 mL) and THF (10 mL) at 0 C, Then, pyridine (0.96 mL, 12.0 mmol) in THF (2 mL) was added dropwisely over 1 h. The resulting mixture was stirred at room temperature overnight. After quenched with water, the mixture was extracted with ethyl acetate, dried over Na2SO4, filtered and concentrated under vacuum. The residue was purified by silica gel chromatography with hexane/ethyl acetate = 20/1 to afford the product.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Di-tert-Butyl malonate, other downstream synthetic routes, hurry up and to see.
