Check Digit Verification of cas no

The CAS Registry Mumber 459-73-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 459-73:
(5*4)+(4*5)+(3*9)+(2*7)+(1*3)=84
84 % 10 = 4
So 459-73-4 is a valid CAS Registry Number.

An efficient approach to diarylethene-amino acid photochromic fluorescent hybrids

Bren, Vladimir A.,Dubonosov, Alexander D.,Kuzmina, Lyudmila G.,Minkin, Vladimir I.,Podshibyakin, Vitaly А.,Shepelenko, Еvgenii N.,Yu. Karlutova, Olga

, (2021)

An effective approach to the synthesis of diarylethene-amino acid hybrids DE-Gly, DE-AABA and DE-DAA (5a-d - 7-a-d) was developed via condensation of furan-2,5-dione-based diarylethenes (DE) and ethyl esters of glycine (Gly), α-aminobutyric acid (AABA) and D-aspartic acid (DAA) with moderate to good yields. According to X-ray diffraction data, DE-Gly hybrid 5a exists in an antiparallel conformation with a distance of 4.549 ? between the reactive carbon atoms C(1)-C(11), potentially capable of forming a single bond, which is suitable for the conrotatory photocyclization reaction allowed by the Woodward-Hoffman rules. The structures of the obtained compounds were proved by 1H, COZY, HSQC, HMBC and 13C NMR spectroscopy. The hybrids DE-Gly, DE-AABA and DE-DAA absorb at 443–456 nm, which corresponds to their existence in a ring-open form O, and display fluorescence at 531–612 nm. Irradiation with light of 436 nm results in their rearrangement into ring-closed colored nonfluorescent isomers C. Backwards re-opening occurs under the action of visible light (λ > 500 nm). Spectral kinetic investigation of 5a,c revealed that the efficiency of photocyclization, as well as the emission quantum yield, decreases with the growth of solvent polarity. The ring-closed isomer C of sterically hindered 5a (R2 = R3 = Me) is stable at room temperature, whereas for 5c (R3 = H), ring opening readily occurs with the speed increasing with the polarity of the solvent. The internal emission of sterically hindered hybrids 5a, 6a and 7a (R2 = R3 = Me) is reversibly modulated in a binary response with good fatigue resistance under successive irradiation with light of 436 and 540 nm.

Copper-induced ammonia N-H functionalization

álvarez, María,álvarez, Eleuterio,Fructos, Manuel R.,Urbano, Juan,Pérez, Pedro J.

, p. 14628 - 14633 (2016)

The activation of ammonia has been achieved with the aid of the TpMsCu core (TpMs = hydrotris(3-mesityl-pyrazolyl)borate). Complexes of the general composition TpMsCu(amine) (1-4) including the ammonia adduct TpMsCu(NH3) (1) have been synthesized and fully spectroscopical- and structurally characterized. Coordinated ammonia in 1 has been reacted with Ph3CPF6 yielding TpMsCu(NH2CPh3) (5) as a result of N-H cleavage and N-C bond formation. In a parallel manner the catalytic functionalization of ammonia with ethyl diazoacetate leading to glycinate derivatives has been developed with TpMsCu(THF) as the catalyst, in the first example of this transformation with ammonia and a copper-based system.

Synthesis of some new 5-arylidene-2,4-thiazolidinedione esters

Tshiluka, Ndivhuwo R.,Bvumbi, Mpelegeng V.,Ramaite, Isaiah I.,Mnyakeni-Moleele, Simon S.

, p. 161 - 175 (2021/03/17)

Compounds containing the 1,3-thiazolidine-2,4-dione scaffold are gaining increasing scientific interest as potential interventional agents for a variety of disease states. A four-step synthesis of ethyl-(2-(5-arylidine-2,4- dioxothiazolidin-3-yl)acetyl)glycinates, alaninates, butanoates, valinates and norvalinates is described. The synthesis began by converting 1,3-thiazolidine-2,4-dione into its potassium salt, which was treated with ethyl (2-chloroacetamido)glycinates, alaninates, butanoates, valinates and norvalinates, respectively, to obtain the penultimate products. These products were then subjected to a Knoevenagel condensation reaction with different aldehydes to obtain the desired products in low to excellent yields.

Stereospecific Synthesis of 3,4-Dihydro-2 H-naphtho-1,4-oxazin-2-ones by Unification of Benzoxepine-4-carboxylates with Chiral Amino Acid Ethyl Esters

Bhimapaka, China Raju,Kasagani, Veera Prasad,Kurma, Siva Hariprasad

supporting information, p. 2976 - 2983 (2020/03/23)

A novel and efficient stereocontrolled method has been developed for the preparation of chiral 3,4-dihydro-2H-naphtho[1,2-b][1,4]oxazin-2-ones by the reaction of benzoxepine-4-carboxylates with chiral amino acid ethyl esters for the first time. The chiral 3,4-dihydro-2H-naphtho-1,4-oxazinones have been achieved in one step by the formation of C-N, C-C, and C-O bonds.
