Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 2133-34-8, C4H7NO2. A document type is Patent, introducing its new discovery., name: (S)-Azetidine-2-carboxylic acid
The invention relates to a racemic – (5 R, 9 S) – 9 – amino – 6 – oxa – 2 – azaspiro [4.5] decane – 2 – carboxylic acid uncle-butylacrylate synthetic method, mainly solves the industrial synthesis method not suitable for the technical problem. The invention is divided into five-step, first of all by the compound 1st step, first of all by the 1 – a benzyloxy – 3 – pyrrolidone and 3 – butene – 1 – ol in the solvent dichloromethane in room temperature reaction to obtain compound 2, 2nd step, compound 2 in methanol, for the catalysis of palladium and hydrogenation to obtain compound 3, 3rd step, for potassium carbonate as the alkali reagent, compound 3 with Boc anhydride, in dichloromethane/water (2:1) in the mixed solvent of reaction to obtain compound 4, 4th step, compound 4 for azido substituted to obtain compound 5, 5th step, compound 5 catalytic hydrogenation to obtain the final target compound 6.
