It can also be used as a catalyst or a ligand in various chemical reactions. (R)-Tert-butyl 4-(2-hydroxyethyl)-2,2-dimethyloxazolidine-3-carboxylate has potential applications in pharmaceutical and agrochemical industries due to its ability to facilitate the production of chiral molecules with high enantioselectivity.

Check Digit Verification of cas no

The CAS Registry Mumber 201404-86-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,4,0 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 201404-86:
(8*2)+(7*0)+(6*1)+(5*4)+(4*0)+(3*4)+(2*8)+(1*6)=76
76 % 10 = 6
So 201404-86-6 is a valid CAS Registry Number.

Paragraph 0065; 0066; 0067; 0076; 0084, (2017/08/25)

The invention discloses a preparation method for a sitagliptin intermediate and belongs to the field of drug synthesis. The preparation method comprises the following steps: (1) carrying out a ring-opening reaction: carrying out Grignard reaction on 2,4,5-trifluorobromobenzene and a Grignard reagent RMgX in a medium of tetrahydrofuran and methyl tertiary-butyl ether at (-20) DEG C to 50 DEG C by taking cuprous chloride as a catalyst, wherein R2 is isopropyl and X is halogen, and then carrying out the ring-opening reaction on the generated compound and a compound shown in a formula 3 to obtain a compound shown in a formula 4; and (2) carrying out an oxidizing reaction: carrying out the oxidizing reaction on the compound shown in the formula 4 and potassium permanganate in an acetone medium, quenching and neutralizing the product by using reducing agents sodium sulfite and sodium hydrogen sulfite, and extracting the product by methyl tertiary butyl ether to obtain the sitagliptin intermediate. The method is low in cost, high in yield, mature in process and suitable for industrial production.
