Check Digit Verification of cas no

The CAS Registry Mumber 72752-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,5 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72752-52:
(7*7)+(6*2)+(5*7)+(4*5)+(3*2)+(2*5)+(1*2)=134
134 % 10 = 4
So 72752-52-4 is a valid CAS Registry Number.

Efficient construction of C=N double bonds via acceptorless dehydrogenative coupling

Sun, Xiang,Hu, Yu,Nie, Shao-Zhen,Yan, Yun-Yun,Zhang, Xue-Jing,Yan, Ming

supporting information, p. 2179 - 2184 (2013/10/01)

The efficient construction of C=N double bonds has been achieved by the Ir-catalyzed intramolecular acceptorless dehydrogenative cross-coupling of tertiary amines and amides. An iridium/2-hydroxypyridine complex was identified as the highly efficient catalyst. A number of quinazolinone derivatives was prepared in excellent yields. An iridium-mediated C-H activation mechanism is proposed. This finding provides an unprecedented strategy for the direct imidation of sp3 C-H bonds.

Design and synthesis of 6-fluoro-2-naphthyl derivatives as novel CCR3 antagonists with reduced CYP2D6 inhibition

Sato, Ippei,Morihira, Koichiro,Inami, Hiroshi,Kubota, Hirokazu,Morokata, Tatsuaki,Suzuki, Keiko,Iura, Yosuke,Nitta, Aiko,Imaoka, Takayuki,Takahashi, Toshiya,Takeuchi, Makoto,Ohta, Mitsuaki,Tsukamoto, Shin-ichi

, p. 8607 - 8618 (2008/12/23)

In our previous study on discovering novel types of CCR3 antagonists, we found a fluoronaphthalene derivative (1) that exhibited potent CCR3 inhibitory activity with an IC50 value of 20 nM. However, compound 1 also inhibited human cytochrome P450 2D6 (CYP2D6) with an IC50 value of 400 nM. In order to reduce its CYP2D6 inhibitory activity, we performed further systematic structural modifications on 1. In particular, we focused on reducing the number of lipophilic moieties in the biphenyl part of 1, using C log D7.4 values as the reference index of lipophilicity. This research led to the identification of N-{(3-exo)-8-[(6-fluoro-2-naphthyl)methyl]-8-azabicyclo[3.2.1]oct-3-yl}-3-(piperidin-1-ylcarbonyl)isonicotinamide 1-oxide (30) which showed comparable CCR3 inhibitory activity (IC50 = 23 nM) with much reduced CYP2D6 inhibitory activity (IC50 = 29,000 nM) compared with 1.

, p. 593 - 597 (2007/10/03)

The development of a large-scale synthesis for (1S)-3-methyl-1-(2- piperidin-1-ylphenyl)butan-1-amine (S-(+)-1), a key intermediate of repaglinide (2), is described. The process conditions for S-(+)-1 involving nucleophilic substitution, Grignard reaction, reduction and resolution were optimized and telescoped. The racemization of the undesired enantiomer R-(-)-1 offers a distinctive advantage in terms of cost and overall yield over the existing process. This communication also describes the control of a DCU byproduct obtained during the condensation of S-(+)-1 with phenyl acetic acid derivative 3 in the synthesis of 2.

A facile route to aryl amines: Nucleophilic substitution of aryl triflates

Schio, Laurent,Lemoine, Guy,Klich, Michel

, p. 1559 - 1562 (2007/10/03)

The aromatic nucleophilic substitution (S(N)Ar) between aryl triflates and secondary amines has been studied. In the absence of solvent, the reaction proceeds at room temperature for nitro and cyano activated aryl triflates and requires higher temperatures in the case of carboxy activation. Variable triflate reactivity could be explained in terms of frontier molecular orbital theory. This methodology has been applied for the synthesis of substituted piperidyl pyridines.

Repaglinide and related hypoglycemic benzoic acid derivatives

Grell, Wolfgang,Hurnaus, Rudolf

, p. 5219 - 5246 (2007/10/03)

The structure-activity relationships in two series of hypoglycemic benzoic acid derivatives (5, 6) were investigated. Series 5 resulted from meglitinide (3) when the 2-methoxy was replaced by an alkyleneimino residue. Maximum activity was observed with the cis-3,5-dimethylpiperidino (5h) and the octamethyleneimino (5l) residues. Series 6 resulted from the meglitinide analogon 4 bearing an inversed amido function when the 2-methoxy, the 5- fluoro, and the α-methyl residue were replaced by a 2-piperidino, a 5- hydrogen, and a larger α-alkyl residue, respectively. An alkoxy residue ortho to the carboxy group further increased activity and duration of action in the rat. The most active racemic compound, 6al (R4 = isobutyl; R = ethoxy), turned out to be 12 times more active than the sulfonylurea (SU) glibenclamide (1). Activity was found to reside predominantly in the (S)- enantiomers. Compared with the SUs 1 and 2 (glimepiride), the most active enantiomer, (S)-6al (AG-EE 623 ZW; repaglinide; ED50 = 10 μg/kg po), is 25 and 18 times more active. Repaglinide turned out to be a useful therapeutic for type 2 diabetic patients; approval was granted recently by the FDA and the EMEA. From investigations on the pharmacophoric groups in compounds of type 5 and 6, it was concluded that in addition to the two already known - the acidic group (COOH; S02NH) and the amidic spacer (CONH; NHCO) - the ortho residue R1 (alkyleneimino; alkoxy; oxo) must be regarded as a third one. A general pharmacophore model suitable for hypoglycemic benzoic acid derivatives, SUs, and sulfonamides is proposed (Figure 6). Furthermore, from superpositions of low-energy conformations (LECs) of 1, 2, and (S)-6al, it was concluded that a common binding conformation (LEC II; Figure 10B) may exist and that differences in binding to the SU receptor and in the mechanism of insulin release between repaglinide and the two SUs may be due to specific hydrophobic differences.
