167255-49-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167255-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,2,5 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 167255-49:
(8*1)+(7*6)+(6*7)+(5*2)+(4*5)+(3*5)+(2*4)+(1*9)=154
154 % 10 = 4
So 167255-49-4 is a valid CAS Registry Number.

Cyclopropane-based conformational restriction of GABA by a stereochemical diversity-oriented strategy: Identification of an efficient lead for potent inhibitors of GABA transports

Nakada, Kazuaki,Yoshikawa, Mamie,Ide, Soichiro,Suemasa, Akihiro,Kawamura, Shuhei,Kobayashi, Takaaki,Masuda, Eiji,Ito, Yoshihiko,Hayakawa, Wataru,Katayama, Takahiro,Yamada, Shizuo,Arisawa, Mitsuhiro,Minami, Masabumi,Shuto, Satoshi

, p. 4938 - 4950 (2013/09/02)

A series of cyclopropane-based conformationally restricted γ-aminobutyric acid (GABA) analogs with stereochemical diversity, that is, the trans- and cis-2,3-methano analogs Ia and Ib and their enantiomers ent-Ia and ent-Ib, and also the trans- and cis-3,4

An expedient asymmetric synthesis of N-protected (S, S)-2-aminomethyl-1- cyclopropanecarboxylic acid

Aitken, David J.,Bull, Steven D.,Davies, Iwan R.,Drouin, Ludovic,Ollivier, Jean,Peed, Jennifer

scheme or table, p. 2729 - 2732 (2010/12/24)

An enantioselective synthesis of a N-Boc-protected trans-cyclopropane γ-amino acid is reported. The key chiral aldehyde intermediate is prepared in enantiomerically pure form using a three-step aldol-cyclopropanation-retro- aldol protocol.

Synthesis of Optically Active cis- and trans-1,2-Disubstituted Cyclopropane Derivatives by the Simmons-Smith Reaction of Allyl Alcohol Derivatives Derived from (R)-2,3-O-Isopropylideneglyceraldehyde

Morikawa, Tsutomu,Sasaki, Hirofumi,Hanai, Ryo,Shibuya, Akira,Taguchi, Takeo

, p. 97 - 103 (2007/10/02)

The Simmons-Smith reactions of Z- and E-allyl alcohol derivatives 6 derived from (R)-2,3-O-isopropylideneglyceraldehyde (5) were used for the synthesis of optically active cis- and trans-1,2-disubstituted cyclopropane derivatives.Reaction of 6 with diethyl zinc and diiodomethane gave cyclopropane derivatives 7 in 84percent to quantitative yields with 35 to ca. 100percent des.Identical facial selectivities toward the double bonds, 1re-2si for Z-6 and 1re-2re for E-6, were observed in the cyclopropanations.The diastereoselectivity was dependent on the protecting group on the terminal allylic oxygen (R of 6, TBDPS > MOM > Bn) and on the stereochemistry of the double bond (Z > E).For TBDPS ethers Z- and E-6c, cis- and trans-7c were obtained as single diastereomers, respectively.It was clearly demonstrated that the stereoselectivity of the cyclopropanation is controlled by the directing effect of the allylic oxygen (O-1) of the dioxolane ring, which coordinates to the reagent.The terminal allylic oxygen (O-2) lowered the diastereoselectivity.This reaction was applied to the synthesis of optically active cyclopropane analogs of γ-aminobutyric acid (GABA) 18, 22, and ent-22.
