143833-82-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143833-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,3 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143833-82:
(8*1)+(7*4)+(6*3)+(5*8)+(4*3)+(3*3)+(2*8)+(1*2)=133
133 % 10 = 3
So 143833-82-3 is a valid CAS Registry Number.

Catalytic diastereoselective reduction of α,β-epoxy and α,β-aziridinyl ynones

Druais, Valerie,Meyer, Christophe,Cossy, Janine

supporting information; scheme or table, p. 516 - 519 (2012/03/26)

The Noyori transfer hydrogenation of α,β-epoxy and α,β-aziridinyl ynones leads to the corresponding α,β-epoxy or α,β-aziridinyl propargylic alcohols with high reagent-controlled diastereoselectivity.

Synthesis of diastereomerically and enantiomerically pure 2,3-disubstituted tetrahydrofurans using a sulfoxonium ylide

Schomaker, Jennifer M.,Pulgam, Veera Reddy,Borhan, Babak

, p. 13600 - 13601 (2007/10/03)

Nucleophilic substitution reactions of 2,3-epoxy alcohols, easily prepared via Sharpless asymmetric epoxidation chemistry, offer access to a wide variety of enantiomerically pure compounds. In this communication, we describe the use of a Payne rearrangement to control regioselectivity in the ring-opening of a series of 2,3-epoxy alcohols with dimethylsulfoxonium methylide to yield diastereomerically and/or enantiomerically pure disubstituted tetrahydrofuran rings. The factors influencing the success and substitution pattern of the THF ring products are discussed, including steric, electronic, and solvent effects. Copyright
