Check Digit Verification of cas no

The CAS Registry Mumber 26734-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,3 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26734-09:
(7*2)+(6*6)+(5*7)+(4*3)+(3*4)+(2*0)+(1*9)=118
118 % 10 = 8
So 26734-09-8 is a valid CAS Registry Number.

Synthesis of oxazolidin-2-ones and imidazolidin-2-ones directly from 1,3-diols or 3-amino alcohols using iodobenzene dichloride and sodium azide

He, Tian,Gao, Wen-Chao,Wang, Wei-Kun,Zhang, Chi

A general and efficient method for the synthesis of oxazolidin-2-ones and imidazolidin-2-ones directly from 1,3-diols and 3-amino alcohols has been developed using the same reagent combination of iodobenzene dichloride (PhICl2) and sodium azide (NaN3).

A new synthesis of bicyclic N,O- and N,S-enaminals by the anionic cyclization of alk-4-ynals with amino alcohols and amino thiols

A reaction of alk-4-ynals with aliphatic amino alcohols or 2-aminoethanethiol in the system DMSO - KOH gives bicyclic N,O- and N,S-enaminals: 6-methylidenehexahydro-2H-pyrrolo[2,1-b][1,3]oxazines, 5-methylidenehexahydropyrrolo[2,1-b]oxazoles, or 5-methyl-

Rhodium-catalyzed asymmetric hydrogenation of olefins with PhthalaPhos, a new class of chiral supramolecular ligands

Pignataro, Luca,Boghi, Michele,Civera, Monica,Carboni, Stefano,Piarulli, Umberto,Gennari, Cesare

supporting information; experimental part, p. 1383 - 1400 (2012/03/27)

A library of 19 binol-derived chiral monophosphites that contain a phthalic acid diamide group (Phthala- Phos) has been designed and synthesized in four steps. These new ligands were screened in the rhodium-catalyzed enantioselective hydrogenation of prochiral dehydroamino esters and enamides. Several members of the library showed excellent enantioselectivity with methyl 2-acetamido acrylate (6 ligands gave >97% ee), methyl (Z)-2- acetamido cinnamate (6 ligands gave >94% ee), and N-(1-phenylvinyl)acetamide (9 ligands gave >95% ee), whilst only a few representatives afforded high enantioselectivities for challenging and industrially relevant substrates N-(3,4-dihydronaphthalen-1- yl)-acetamide (96% ee in one case) and methyl (E)-2-(acetamidomethyl)-3- phenylacrylate (99% ee in one case). In most cases, the new ligands were more active and more stereoselective than their structurally related monodentate phosphites (which are devoid of functional groups that are capable of hydrogen-bonding interactions). Control experiments and kinetic studies were carried out that allowed us to demonstrate that hydrogen-bonding interactions involving the diamide group of the PhthalaPhos ligands strongly contribute to their outstanding catalytic properties. Computational studies carried out on a rhodium precatalyst and on a conceivable intermediate in the hydrogenation catalytic cycle shed some light on the role played by hydrogen bonding, which is likely to act in a substrate-orientation effect.

Continuous amination of propanediols in supercritical ammonia

Fischer, Achim,Mallat, Tamas,Baiker, Alfons

, p. 351 - 354 (2007/10/03)

Enhancements in selectivity by a factor of 4 to 18 were observed in the near critical regions of ammonia during the Co- and Ni-catalyzed synthesis of 1,3-diamino-propanes. These results are attributed to the higher concentration of ammonia at the surface of the catalyst, which favors the amination and suppresses degredation reactions.

Cyclic Organophosphorus Compounds XVII. The Mass Spectra of Some 5,5-Dimethyl-perhydro-1,3,2-oxazaphosph(v)orines

Enamines of 3,3-Dimethylazetidine

Thompson, Hugh W.,Swistok, Joseph

, p. 4907 - 4911 (2007/10/02)

In an improvement over previous procedures, 3,3-dimethylazetidine (3) has been synthesized in 26percent yield from ethyl cyanoacetate.Rates of formation for the enamines of 3 and of pyrrolidine with 2-methylcyclohexanone (1) and 1-tetralone (2) have been studied.The 5- to 10-fold rate increase observed for 3 is attributed to diminished steric hindrance relative to pyrrolidine.Compared to the enamines of pyrrolidine with 1 and 2, those of 3 methylate initially on nitrogen to ggreater degree and are less selective for monomethylation.The enamine formed between 1 and 3 exists at equilibrium as an 83.17 mixture of tri- and tetrasubstituted isomers, in which the less substituted isomer has its vinyl H 1H NMR peak at δ 4.10.These properties are compared to those of other enamines of 1, in which a predictive relationship had previously been suggested.
