Adding a certain compound to certain chemical reactions, such as: 676371-64-5, name is Methyl 3-((tert-butoxycarbonyl)amino)bicyclo[1.1.1]pentane-1-carboxylate, belongs to amides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 676371-64-5, SDS of cas: 676371-64-5
To a stirring solution of methyl 3-((tert- butoxycarbonyl)amino)bicyclo[1 .1 1 ]pentane-1 -carboxylate (0.2 g, 0.829 mmol) in THF (3.0 ml_), under nitrogen, in an ice bath was slowly added methylmagnesium bromide (3 M in Et20, 5 ml_, 3.32 mmol). After addition, the reaction mixture was stirred in the ice bath for ~10 min and then at rt for ~30 mins. The reaction was quenched with sat. aq. ammonium chloride and extracted with ethyl acetate. The organic phase was washed with brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure to give crude tert- butyl (3-(2-hydroxypropan-2-yl)bicyclo[1 .1 1 ]pentan-1 -yl)carbamate (187 mg, 0.775 mmol, 93 % yield) as a colorless oil. 1H NMR (400 MHz, CD3SOCD3) d ppm 7.39 (br. s., 1 H), 4.1 1 (s, 1 H), 1 .70 (s, 6 H), 1 .37 (s, 9 H), 1 .03 (s, 6 H).
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, Methyl 3-((tert-butoxycarbonyl)amino)bicyclo[1.1.1]pentane-1-carboxylate, other downstream synthetic routes, hurry up and to see.
