1195-66-0 - Reference Information
| Use | 2-methoxy-4, 4,5, 5-tetramethyl-1, 3, 2-dioxyborane is a drug intermediate. |
| preparation | 2-methoxy-4, 4,5, 5-tetramethyl-1, 3, 2-dioxoborane can be obtained by one-step preparation of borane, a cyano alcohol, and dimethyl carbonate. It is possible to use the preparation of clenbuterol intermediates. under a nitrogen atmosphere, the catalyst La[N(SiMe3)2]3(3.1mg,0.005mmol) was added to the reaction flask after dehydration deoxygenation, add dimethyl carbonate (84.2 μL,1mmol) with a pipette, then add enoxanol borane (478.8 μL,3.3mmol) with a pipette, react at room temperature for 6h, contact with air to stop the reaction, A drop was drawn into the nuclear magnetic tube with a dropper, and CDCl3 was added to form a solution. The 1H spectrum yield was calculated to be 99%. NMR data for the product: 1H NMR (1.18 MHz,CDCl3) Δ3.53 (s,9H,CH3OBpin), (s,40H,OBpin). |
