General Description
(S)-2,2'-BINAPHTHYL-20-CROWN-6 is a chiral, macrocyclic compound that is specifically designed to bind alkali metal cations such as potassium and sodium. It consists of a 20-membered crown ether ring with two binaphthyl units attached, leading to its chiral nature. (S)-2,2'-BINAPHTHYL-20-CROWN-6 is often used as a chiral selector in enantioselective separations and as a chiral receptor in asymmetric catalysis. Its ability to selectively bind certain metal cations makes it useful in various chemical processes and analytical techniques. Additionally, its unique structure and chiral properties make it a valuable tool in the field of organic chemistry for studying molecular recognition and chiral interactions.
Check Digit Verification of cas no
The CAS Registry Mumber 41024-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,0,2 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41024-92:
(7*4)+(6*1)+(5*0)+(4*2)+(3*4)+(2*9)+(1*2)=74
74 % 10 = 4
So 41024-92-4 is a valid CAS Registry Number.

Synthesis, Rapid Resolution, and Determination of Absolute Configuration of Racemic 2,2'-Binaphthyldiyl Crown Ethers and Analogues via β-Cyclodextrin Complexation

Twenty racemic and four diastereomeric 2,2'-binaphthyldiyl crown ethers and analogues were synthesized.Chiral interactions between these compounds and immobilized β-cyclodextrin were examined.Thirteen of the enantiomeric pairs and two of the diastereomers were successfully resolved.It was found that relatively small changes in the structure of these compounds could have large effects on chiral recognition.In general, the (-)-S enantiomers formed stronger inclusion complexes with β-cyclodextrin than did the (+)-R enantiomers.
