13861-75-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13861-75-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,6 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13861-75:
(7*1)+(6*3)+(5*8)+(4*6)+(3*1)+(2*7)+(1*5)=111
111 % 10 = 1
So 13861-75-1 is a valid CAS Registry Number.

Vinyl Thianthrenium Tetrafluoroborate: A Practical and Versatile Vinylating Reagent Made from Ethylene

Juliá, Fabio,Yan, Jiyao,Paulus, Fritz,Ritter, Tobias

supporting information, p. 12992 - 12998 (2021/09/03)

The use of vinyl electrophiles in synthesis has been hampered by the lack of access to a suitable reagent that is practical and of appropriate reactivity. In this work we introduce a vinyl thianthrenium salt as an effective vinylating reagent. The bench-stable, crystalline reagent can be readily prepared from ethylene gas at atmospheric pressure in one step and is broadly useful in the annulation chemistry of (hetero)cycles, N-vinylation of heterocyclic compounds, and palladium-catalyzed cross-coupling reactions. The structural features of the thianthrene core enable a distinct synthesis and reactivity profile, unprecedented for other vinyl sulfonium derivatives.

Paragraph 234, (2021/11/06)

The present invention provides novel poly(ADP-ribose) polymerase (PARP) inhibitors, methods of preparing them, pharmaceutical compositions containing them and methods for the treatment, prevention and/or amelioration of PARP mediated diseases or disorders using them. In particular, the compounds described herein are useful for the treatment of carcinoma of the breast, ovarian cancer, carcinoma of the liver, carcinoma of the lung, small cell lung cancer, esophageal cancer, gall bladder cancer, pancreatic cancer and stomach cancer.

Rhodium(III)-Catalyzed Cyclopropane C-H/C-C Activation Sequence Provides Diastereoselective Access to α-Alkoxylated γ-Lactams

Audic, Benoit,Cramer, Nicolai

, p. 5030 - 5034 (2020/07/04)

A Cp*Rh(III)-catalyzed C-H/C-C bond activation sequence of cyclopropyl hydroxamates has been developed. The three-component process allows trapping of the intermediate rhodacycle with diazomalonates and an alcohol nucleophile to provide access to synthetically valuable α-alkoxylated γ-lactams with trans diastereoselectivity.
