130721-60-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130721-60-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,2 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130721-60:
(8*1)+(7*3)+(6*0)+(5*7)+(4*2)+(3*1)+(2*6)+(1*0)=87
87 % 10 = 7
So 130721-60-7 is a valid CAS Registry Number.

Efficient 1,3-Oxazolidin-2-one Synthesis through Heterogeneous PdII-Catalyzed Intramolecular Hydroamination of Propargylic Carbamates

Oschmann, Michael,Placais, Clotilde,Nagendiran, Anuja,B?ckvall, Jan-E.,Verho, Oscar

supporting information, p. 6295 - 6299 (2019/05/08)

Herein, we present an operationally simple protocol for the cycloisomerization of propargylic carbamates in which a heterogeneous catalyst consisting of Pd species immobilized on amino-functionalized siliceous mesocellular foam (PdII-AmP-MCF) i

Scalable synthesis of oxazolones from propargylic alcohols through multistep palladium(II) catalysis: β-selective oxidative heck coupling of cyclic sulfonyl enamides and aryl boroxines

Alamsetti, Santosh Kumar,Persson, Andreas K. A.,Jiang, Tuo,Baeckvall, Jan-E.

supporting information, p. 13745 - 13750 (2014/01/06)

A whale of a scale: The title oxidative Heck coupling proceeded with unusual β selectivity to generate a variety of branched substituted oxazolones (see scheme; Ts=p-toluenesulfonyl). The three-step synthesis from readily available starting materials with a simple palladium catalyst and inexpensive reagents could be carried out in a single reaction vessel or scaled up for the preparation of large amounts of these amino acid precursors.

Convenient synthesis of 4-methylene-2-oxazolidinones and 4-methylenetetrahydro-1,3-oxazin-2-ones via transition-metal catalyzed intramolecular addition of nitrogen atom to actylenic triple bond

Tamaru,Kimura,Tanaka,Kure,Yoshida

, p. 2838 - 2849 (2007/10/02)

2-Propynyl tosylcarbamates 1 undergo cyclization smoothly by the catalysis of CuCl/Et3N or AgNCO/Et3N to furnish 4-methylene-2-oxazolidinones 2 in good yields. The similar cyclization of the N-acyl derivatives of 1 (PhCO, MeCO, EtOCO, etc.) is catalyzed effectively by AgNCO/t-BuOK. These reactions accommodate a variety of substituents at C1 and C3 of 2-propyn-1-ol and provide (Z)-2 as single stereoisomers. The scope of the cyclization of 3-butynyl carbamates is rather limited, and in general only N-tosyl derivatives of terminally unsubstituted 3-butyn-1-ols undergo cyclization to give 4-methylenetetrahydro-1,3-oxazin-2-ones in synthetically useful yields by the catalysis of AgNCO/Et3N or AgNCO/t-BuOK.
