111292-87-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111292-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,9 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 111292-87:
(8*1)+(7*1)+(6*1)+(5*2)+(4*9)+(3*2)+(2*8)+(1*7)=96
96 % 10 = 6
So 111292-87-6 is a valid CAS Registry Number.

A stereoselective synthesis of the C11-C19 fragment of (+)-peloruside A

Chen, Zhen-liang,Zhou, Wei-shan

, p. 5289 - 5292 (2006)

A new route to the synthesis of the C11-C19 fragment of peloruside A is described, which includes an aldol reaction with ethyl acetoacetate, β-hydroxyl-directed reduction of β-hydroxy ketone, as well as methylation of C13 hydroxyl moiety in the system of

Asymmetric total synthesis of four stereoisomers of the sex pheromone of the western corn rootworm

Sun, Zhi-Feng,Zhang, Tao,Liu, Jinyang,Du, Zhen-Ting,Zheng, Huaiji

, (2018)

A convergent synthesis of four stereoisomers of the sex pheromone of the western corn rootworm (8-methyldecan-2-yl propionate, 1) from commercially available chiral starting materials is reported. The key step was Julia–Kocienski olefination between chiral BT-sulfone and chiral aldehyde. This synthetic route provided the four stereoisomers of 1 in 24–29% total yield via a six-step sequence. The simple scale-up strategy provides a new way to achieve the asymmetric synthesis of the sex pheromone.

Synthesis of (+)-Tacamonine via Stereoselective Radical Cyclization

Smith, Myles W.,Ferreira, Jasmin,Hunter, Roger,Venter, Gerhard A.,Su, Hong

, p. 8740 - 8745 (2019)

A concise, asymmetric synthesis of the indole alkaloid (+)-tacamonine is reported involving a stereoselective radical cyclization of a 1-phenylsulfanyl tetrahydro-β-carboline bearing a pendant enoate ester side chain as a key step. In this process, a sing

Enantioselective Aza-Heck Cyclizations of N-(Tosyloxy)carbamates: Synthesis of Pyrrolidines and Piperidines

Ma, Xiaofeng,Hazelden, Ian R.,Langer, Thomas,Munday, Rachel H.,Bower, John F.

supporting information, p. 3356 - 3360 (2019/03/07)

Pd(0)-systems modified with SPINOL-derived phosphoramidate ligands promote highly enantioselective aza-Heck cyclizations of alkenyl N-(tosyloxy)carbamates. The method provides versatile access to challenging N-heterocycles and represents the broadest scope enantioselective aza-Heck protocol developed to date.
