870091-89-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 870091-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,0,9 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 870091-89:
(8*8)+(7*7)+(6*0)+(5*0)+(4*9)+(3*1)+(2*8)+(1*9)=177
177 % 10 = 7
So 870091-89-7 is a valid CAS Registry Number.

Total synthesis of beauveriolide I

Tian, Hua,Jiao, Xiaozhen,Xie, Ping,Liang, Xiaotian

, p. 8579 - 8581 (2005)

The first total synthesis of beauveriolide I (1a), a selective ACAT inhibitor, is described. The key steps in this synthesis involved a diastereoselective aldol condensation sequence and a macrocyclization.

Studies towards the Synthesis of (-)-Pulvomycin: Construction of the C12-C40 Segment by a Stereoselective Aldol Reaction

Wienhold, Sebastian,Fritz, Lukas,Judt, Tatjana,Hackl, Sabrina,Neubauer, Thomas,Sauerer, Bastian,Bach, Thorsten

, p. 4246 - 4262 (2021)

A convergent strategy was developed for the synthesis of the C12 C40 segment of ( )-pulvomycin. Key step was a diastereoselective aldol reaction between a chiral ethyl ketone representing the C24 C40 fragment and a chiral aldehyde representing the C12 C23

Stereocontrolled synthesis of the C1-C7 fragment of enigmazole a

Kishi, Takayuki,Fujisawa, Yuka,Takamura, Hiroyoshi,Kadota, Isao

, p. 515 - 522 (2014/03/21)

An enantio- and stereoselective synthesis of the C1-C7 fragment of enigmazole A is described. The three asymmetric centers of the molecule were constructed efficiently by using Evans chiral auxiliary protocol.

Total syntheses of 28,29-diepi-arenamide A, 29-epi-arenamide A, and 28-epi-arenamide A

Jithender Reddy, V.,Pradhan, Tapan Kumar,Ghosh, Subhash

, p. 6148 - 6150,3 (2020/08/20)

This communication describes the synthesis of stereochemical analogs of arenamide A, a 19-membered cytotoxic depsipeptide isolated from the fermentation broth of a marine bacterial strain Salinispora arenicola. The key steps are diastereoselective aldol r

An improved synthesis of (-)-brevisamide, a marine monocyclic ether amide of dinoflagellate origin

Tsutsumi, Ryosuke,Kuranaga, Takefumi,Wright, Jeffrey L.C.,Baden, Daniel G.,Ito, Emiko,Satake, Masayuki,Tachibana, Kazuo

experimental part, p. 6775 - 6782 (2010/10/02)

An improved synthesis of (-)-brevisamide a marine cyclic ether isolated from the red-tide dinoflagellate Karenia brevis was achieved. The ether ring portion was constructed from an unsaturated lactone, which was prepared enantioselectively via an Evans aldol reaction and one-pot lactonization in the presence of excessive base after an Ando reaction. The ether ring and a dienol side chain fragment were connected via Suzuki-Miyaura coupling.

Asymmetric synthesis of the C1-C13 fragment of the marine metabolite bistramide K

Bauder, Claude

experimental part, p. 6207 - 6216 (2010/12/25)

A synthetic study on the construction of the C1-C13 fragment of bistramide K is described. This unit differs from other members of the bistramide family, which are equipped with a pyran structure at C6-C11. In bistramide K, the linear C1-C13 portion conta

A general synthetic approach for the synthesis of β-hydroxy-δ-lactones: asymmetric total synthesis of prelactones and epi-prelactones V and E

Sabitha, Gowravaram,Padmaja,Reddy, K. Bhaskar,Yadav

, p. 919 - 922 (2008/09/17)

A general synthetic approach for the synthesis of prelactones and epi-prelactones V and E has been reported using an Evans' aldol reaction as the key step.

Total synthesis of (-)-ulapualide A, a novel tris-oxazole macrolide from marine nudibranchs, based on some biosynthesis speculation
