157790-73-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157790-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,9 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 157790-73:
(8*1)+(7*5)+(6*7)+(5*7)+(4*9)+(3*0)+(2*7)+(1*3)=173
173 % 10 = 3
So 157790-73-3 is a valid CAS Registry Number.

Directed ortho Metalation (D o M)-Linked Corriu-Kumada, Negishi, and Suzuki-Miyaura Cross-Coupling Protocols: A Comparative Study

Quesnelle, Claude A.,Snieckus, Victor

supporting information, p. 4395 - 4412 (2018/11/21)

A systematic study of the widely used, titled name reaction transition-metal-catalyzed cross-coupling reactions with attention to context with the directed ortho metalation (D o M) is reported. In general, the Suzuki-Miyaura and Negishi protocols show gre

Efficient cross-coupling of aryl/alkenyl triflates with acyclic secondary alkylboronic acids

Si, Tengda,Li, Bowen,Xiong, Wenrui,Xu, Bin,Tang, Wenjun

supporting information, p. 9903 - 9909 (2017/12/12)

Aryl-secondary alkyl cross-coupling with aryl sulfonate esters as coupling partners remains a significant challenge. Efficient cross-coupling between aryl/alkenyl triflates and acyclic secondary alkylboronic acids is realized for the first time to provide a series of sterically congested acyclic secondary alkyl arenes/olefins in good to excellent yields. The employment of sterically bulky P,PO ligand L1/L2 is crucial for the high yields and selectivities. The method has enabled a concise and 4-step synthesis of a key intermediate of male contraceptive agent and PAF antagonist gossypol.

The conversion of phenols to the corresponding aryl halides under mild conditions

Thompson, Alicia L. S.,Kabalka, George W.,Akula, Murthy R.,Huffman, John W.

Mild, novel procedures have been developed for the syntheses of aryl halides from the corresponding phenols in modest to good yields via boronate ester intermediates.

A high throughput synthesis of aryl triflate and aryl nonaflate promoted by a polymer supported base (PTBD)
