94897-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 94897-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,9 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 94897-34:
194 % 10 = 4
So 94897-34-4 is a valid CAS Registry Number.

Chiral isoxazolidine-mediated stereoselective umpolung α-phenylation of methyl ketones

Takeda, Norihiko,Furuishi, Mizuki,Nishijima, Yuri,Futaki, Erika,Ueda, Masafumi,Shinada, Tetsuro,Miyata, Okiko

supporting information, p. 8940 - 8943 (2018/12/10)

An effective asymmetric α-phenylation of methyl ketones with triphenylaluminium in the presence of (+)-benzopyranoisoxazolidine has been developed. The reaction proceeds via the in situ formation of a chiral N-alkoxyenamine and the subsequent diastereoselective nucleophilic phenylation to provide α-phenylated products in moderate to good yields, with high enantioselectivities.

Discovery of N-[(1S,2S)-3-(4-chlorophenyl)-2-(3-cyanophenyl)-1- methylpropyl]-2-methyl-2-{[5-(trifluoromethyl)pyridin-2-yl]oxy}propanamide (MK-0364), a novel, acyclic cannabinoid-1 receptor inverse agonist for the treatment of obesity

The discovery of novel acyclic amide cannabinoid-1 receptor inverse agonists is described. They are potent, selective, orally bioavailable, and active in rodent models of food intake and body weight reduction. A major focus of the optimization process was to increase in vivo efficacy and to reduce the potential for formation of reactive metabolites. These efforts led to the identification of compound 48 for development as a clinical candidate for the treatment of obesity.

Reduction of diaryl alkenes by hypophosphorous acid-iodine in acetic acid

Fry, Albert J.,Allukian, Myron,Williams, Allison D.

, p. 4411 - 4415 (2007/10/03)

A mixture of 50% aqueous H3PO2 and I2 (in catalytic amount) in HOAc efficiently reduces aryl alkenes to the corresponding alkanes in high yield. Addition of acetic anhydride to the medium results in ring-acetylation (or N-acetylation in the case of amines). H3PO2 costs only one-fifth as much as hydriodic acid on a mole basis and one mole of H3PO2 produces four moles of HI, resulting in a 20-fold cost advantage for H3PO2/I2 over aqueous HI as a source of HI.
