42238-15-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42238-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,3 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42238-15:
(7*4)+(6*2)+(5*2)+(4*3)+(3*8)+(2*1)+(1*5)=93
93 % 10 = 3
So 42238-15-3 is a valid CAS Registry Number.

Preparation and reactions of 2'- and 3'-vinyl bromides of uracil-nucleosides: Versatile synthons for anti-HIV agents

Haraguchi,Itho,Tanaka,Miyasaka

, p. 3391 - 3394 (1991)

Bromination and successive oxidation of 1-[5-O-(t-butyldiphenyl-silyl)-3-deoxy-3-phenylseleno-β-D-xylofuranos yl]uracil yields the 2'- and 3'-vinyl bromides, which serve as synthons for 2'- or 3'-substituted 2',3'-didehydro-2',3'-dideoxyuridines via palla

Multicatalytic approach to one-pot stereoselective synthesis of secondary benzylic alcohols

Casnati, Alessandra,Lichosyt, Dawid,Lainer, Bruno,Veth, Lukas,Dydio, Pawe?

supporting information, p. 3502 - 3506 (2021/05/10)

One-pot procedures bear the potential to rapidly build up molecular complexity without isolation and purification of consecutive intermediates. Here, we report multicatalytic protocols that convert alkenes, unsaturated aliphatic alcohols, and aryl boronic acids into secondary benzylic alcohols with high stereoselectivities (typically >95:5 er) under sequential catalysis that integrates alkene cross-metathesis, isomerization, and nucleophilic addition. Prochiral allylic alcohols can be converted to any stereoisomer of the product with high stereoselectivity (>98:2 er, >20:1 dr).

Synergistic Relay Reactions To Achieve Redox-Neutral α-Alkylations of Olefinic Alcohols with Ruthenium(II) Catalysis

Kan, Jian,Li, Chao-Jun,Li, Chen-Chen,Li, Jianbin,Lv, Leiyang,Qiu, Zihang

supporting information, p. 4544 - 4549 (2020/02/04)

Herein, we report a ruthenium-catalyzed redox-neutral α-alkylation of unsaturated alcohols based on a synergistic relay process involving olefin isomerization (chain walking) and umpolung hydrazone addition, which takes advantage of the interaction between the two rather inefficient individual reaction steps to enable an efficient overall process. This transformation shows the compatibility of hydrazone-type “carbanions” and active protons in a one-pot reaction, and at the same time achieves the first Grignard-type nucleophilic addition using olefinic alcohols as latent carbonyl groups, providing a higher yield of the corresponding secondary alcohol than the classical hydrazone addition to aldehydes does. A broad scope of unsaturated alcohols and hydrazones, including some complex structures, can be successfully employed in this reaction, which shows the versatility of this approach and its suitability as an alternative, efficient means for the generation of secondary and tertiary alcohols.
