400724-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 400724-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,2 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 400724-21:
(8*4)+(7*0)+(6*0)+(5*7)+(4*2)+(3*4)+(2*2)+(1*1)=92
92 % 10 = 2
So 400724-21-2 is a valid CAS Registry Number.

Diastereoselective synthesis of 2-alkylated 4-silyloxyproline esters

Sato,Kawasaki,Oda,Yagi,El Bialy,Uenishi,Yamauchi,Ikeda

, p. 2623 - 2631 (2001)

Treatment of the 4-silyloxy-N-Boc-L-proline methyl ester 1 with allyl bromide in the presence of LDA in THF at -78°C gives a mixture of the (2S,4R)- and (2R,4R)-2-(prop-2-enyl)-4-silyloxy-N-Boc-L-proline esters 2a and 2b in 75% combined yield in the ratio 53:47. In contrast, similar treatment of the (-)- and (+)-menthyl esters 5 and 6 gives a mixture of allylated products 7a,b and 8a,b in the ratio 75:25 and 89:11, respectively. Reaction of 6 with methyl iodide and propyl iodide also give the corresponding 2-alkylated esters 16a and 16b in a highly diastereoselective manner (94:6 and 93:7, respectively).
