148700-84-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 148700-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,7,0 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 148700-84:
(8*1)+(7*4)+(6*8)+(5*7)+(4*0)+(3*0)+(2*8)+(1*4)=139
139 % 10 = 9
So 148700-84-9 is a valid CAS Registry Number.

Synthesis of 2-Arylpiperidines via pd-catalyzed arylation of aza-Achmatowicz rearrangement products with arylboronic acids

Zhao, Guodong,Canterbury, Daniel P.,Taylor, Alexandria P.,Cheng, Xiayun,Mikochik, Peter,Bagley, Scott W.,Tong, Rongbiao

, p. 458 - 463 (2020/01/21)

The first Pd-catalyzed arylation of aza-Achmatowicz rearrangement products with arylboronic acids is achieved, providing versatile 2-Aryldihydropyridinones for facile synthesis of highly functionalized 2-Arylpiperidines. Key to this arylation is the use of non-phosphine-ligand palladium precatalyst. The substrate scope is demonstrated with >26 examples, and the utility of 2-Aryldihydropyridinones is illustrated by the synthesis of a small collection of 2-Arylpiperidines with substituents or functional groups at any carbon (C2-C6) as well as two NK1 receptor antagonists (+)-CP-999,94 and (+)-L-733,060.

Divergent syntheses of L-733, 060 and CP-122721 from functionalized pieridinones made by one-pot tandem cyclization

Liu, Yi-Wen,Mao, Zhuo-Ya,Ma, Rui-Jun,Yan, Jia-Hang,Si, Chang-Mei,Wei, Bang-Guo

, p. 2100 - 2108 (2017/03/17)

An efficient diastereoselective approach to access trans-5-hydroxy-6-substituted 2-piperidinones skeleton has been developed through one-pot intramolecular tandem process of O-benzyl protected aldimine 11 with Grignard reagents. The diastereoselectivity of substitution at C-6 position of 2-piperidinone was controlled by α-benzyloxy group. In addition, the utility of this straightforward cascade process is demonstrated by the asymmetric syntheses of (+)-L-733, 060 (2) and its 2-substituted analogue 3, as well as (+)-CP-122721 (5).

Concise enantioselective syntheses of (+)-L-733,060 and (2 S,3 S)-3-hydroxypipecolic acid by cobalt(III)(salen)-catalyzed two-stereocenter hydrolytic kinetic resolution of racemic azido epoxides

Devalankar, Dattatray A.,Chouthaiwale, Pandurang V.,Sudalai, Arumugam

, p. 102 - 104 (2014/01/06)

An efficient synthesis of the 2,3-disubstituted piperidines (+)-L-733,060 and (2S,3S)-3-hydroxypipecolic acid (≥99% ee) in high optical purity from commercially available starting materials is described. The strategy involves a cobalt-catalyzed hydrolytic
