699-01-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 699-01-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 699-01:
(5*6)+(4*9)+(3*9)+(2*0)+(1*1)=94
94 % 10 = 4
So 699-01-4 is a valid CAS Registry Number.

Enantioselective Resolution Copolymerization of Racemic 2,3-Disubstituted cis-Epoxides with CO2 Mediated by Binuclear Cobalt(III) Catalyst?

He, Guang-Hui,Liu, Yan-Lan,Liu, Ye,Lu, Xiao-Bing

, p. 2386 - 2390 (2021/07/12)

Enantioselective resolution copolymerization of racemic internal epoxides with carbon dioxide (CO2) is a challenging issue because of their poor reactivity and complicated regio/stereoselectivity. Herein, we describe the first enantioselective

Synthesis of Substituted β-Functionalised Styrenes by Microwave-Assisted Olefin Cross-Metathesis and Scalable Synthesis of Apremilast

Jana, Anupam,Zieliński, Grzegorz Krzysztof,Czarnocka-?niada?a, Sylwia,Grudzień, Krzysztof,Podwysocka, Dominika,Szulc, Marcin,Kajetanowicz, Anna,Grela, Karol

, p. 5808 - 5813 (2019/11/03)

Preparation of diversely substituted β-functionalised styrenes by microwave-assisted olefin cross-metathesis (CM) is described. This method can be also employed in the synthesis of β-deuterated α,β-unsaturated sulfones from inexpensive allylbenzenes, though unprecedented one-pot isomerisation/deuteration/cross-metathesis sequence. One of such obtained CM products has been utilised in a new scalable synthesis of Apremilast (6), a potent and orally active phosphodiesterase 4 and tumour necrosis factor-α inhibitor. The same strategy was used in synthesis of an optical antipode of 6, ent-Apremilast.

Alkene functionalization for the stereospecific synthesis of substituted aziridines by visible-light photoredox catalysis

Yu, Wan-Lei,Chen, Jian-Qiang,Wei, Yun-Long,Wang, Zhu-Yin,Xu, Peng-Fei

supporting information, p. 1948 - 1951 (2018/03/01)

A novel strategy involving visible-light-induced functionalization of alkenes for the synthesis of substituted aziridines was developed. The readily prepared N-protected 1-aminopyridinium salts were used for the generation of N-centered radicals. This approach allowed the synthesis of aziridines bearing various functional groups with excellent diastereoselectivity under mild conditions. Moreover, this protocol was successfully applied to prepare structurally diverse nitrogen-containing frameworks.
