65878-65-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65878-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,7 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65878-65:
(7*6)+(6*5)+(5*8)+(4*7)+(3*8)+(2*6)+(1*5)=181
181 % 10 = 1
So 65878-65-1 is a valid CAS Registry Number.

Catalytic Asymmetric Formal Insertion of Aryldiazoalkanes into the C-H Bond of Aldehydes: Synthesis of Enantioenriched Acyclic α-Tertiary Aryl Ketones

Kang, Byung Chul,Nam, Dong Guk,Hwang, Geum-Sook,Ryu, Do Hyun

supporting information, p. 4810 - 4813 (2015/10/12)

A novel, catalytic enantioselective route to synthesize a variety of α-tertiary aryl ketones via a boron Lewis acid promoted formal insertion of aryldiazoalkane into the C-H bond of both aromatic and aliphatic aldehydes is described. In the presence of ch

[1,2]-Wittig rearrangement of enantio-defined α-alkoxyalkyllithiums: Structural requirement and steric course at the Li-bearing terminus

Tomooka, Katsuhiko,Igarashi, Tatsuya,Nakai, Takeshi

, p. 5927 - 5932 (2007/10/02)

The [1,2]-Wittig rearrangements of enantio-defined α-benzyloxypropyllithium and its (R)-α-methylbenzyloxy analogs, generated from the enantio-enriched stannanes via Sn/Li exchange, are shown to proceed predominantly with inversion of configuration at the

A new type of complex reagent, R4Pb / TiCl4

Yamamoto, Yoshinori,Yamada, Jun-Ichi,Asano, Tetsuya

, p. 5587 - 5596 (2007/10/02)

Tetraalkllleads (R4Pb) reacted quite smoothly with aldehydes R'CHO in the presence of TiCl4 to produce the corresponding alcohols (RCHOHR′) in high to good yields. The reagent system, R4Pb/ TiCl4, exhibited high chemoselectivity; only aldehydes underwent the alkylation in the presence of ketones. Further, the new reagent exhibited high 1,2- and 1,3-asymmetric induction. The transfer order of alkyl groups in the reaction of aldehydes with mixed tetraalkylleads/TiCl4 was determined; Me>Et.i-Pr?n-Bu.
