18243-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18243-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,4 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18243-59:
(7*1)+(6*8)+(5*2)+(4*4)+(3*3)+(2*5)+(1*9)=109
109 % 10 = 9
So 18243-59-9 is a valid CAS Registry Number.

Synthesis of potentially biologically active 6-(1,3-butadiynyl)purines

K?ová?ek,Dvo?ák

, p. 40 - 47 (2015)

1,3-Alkadiynyl(trimethyl)silanes were prepared by the Negishi or Sonogashira reactions of bromoethynyl (trimethyl)silane with several terminal alkynes in 34-75% yield. However, the direct Hiyama coupling of these compounds with 6-iodopurine derivatives ha

Stereoselective synthesis of (E)- and (Z)-acetals of pent-2-en-4-yn-1-al and related dienynes and dienediynes

Suzenet, Franck,Parrain, Jean-Luc,Quintard, Jean-Paul

, p. 2957 - 2963 (1999)

(3E)-5,5-Diethoxypent-3-en-1-yne was stereospecifically prepared by Sonogashira-Linstrumelle cross-coupling between (E)-3-iodoacrolein diethylacetal and (trimethylsilyl)acetylene. The (Z) isomer was obtained by Stille cross-coupling between the corresponding (Z)-vinyltin and 1-bromo-2- (trimethylsilyl)acetylene. In the case of the (E) isomer, transacetalisation occurred without isomerization affording a large variety of (E)-enynals protected as acetals. It has also been shown to be possible to obtain the corresponding (E,E)-dienediyne through sp-sp homo-coupling under appropriate experimental conditions.

Catalytic Asymmetric Hydroacyloxylation/Ring-Opening Reaction of Ynamides, Acids, and Aziridines

Li, Xiangqiang,Zeng, Hongkun,Lin, Lili,Feng, Xiaoming

supporting information, p. 2954 - 2958 (2021/05/05)

A highly enantioselective three-component reaction of ynamides with carboxylic acids and 2,2′-diester aziridines has been realized by using a chiral N,N′-dioxide/Ho(OTf)3 complex as a Lewis acid catalyst. The process includes the formation of an α-acyloxyenamide intermediate through the addition of carboxylic acids to ynamides and the following enantioselective nucleophilic addition to in-situ-generated azomethine ylides induced by the chiral catalyst. A range of amino acyloxyenamides are delivered in moderate to good yields with good ee values. In addition, a possible catalytic cycle with a transition model is proposed to elucidate the reaction mechanism.
