Check Digit Verification of cas no

The CAS Registry Mumber 118916-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,1 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118916-60:
(8*1)+(7*1)+(6*8)+(5*9)+(4*1)+(3*6)+(2*6)+(1*0)=142
142 % 10 = 2
So 118916-60-2 is a valid CAS Registry Number.

The first enantioselective approach to 13a-methyl-14- hydroxyphenanthroindolizidine alkaloids - Synthetic studies towards hypoestestatin 2

Su, Bo,Deng, Meng,Wang, Qingmin

, p. 1979 - 1985 (2013)

The first enantioselective approach to 13a-methyl-14- hydroxyphenanthroindolizidine alkaloids was achieved in six linear steps from phenanthryl alcohol and features a highly substrate-dependent Parham cycloacylation and Seebach's enantioselective alkylation as the key steps. The route is concise, protecting-group free, provides access to all stereoisomers, and works on a gram scale. In addition to the putative structure of hypoestestatin 2, the other three stereoisomers and two structurally related analogues were synthesized, none of which shows identical NMR spectra to those reported for natural hypoestestatin 2, which indicates that further structure revision is required. By using Seebach's stereoselective alkylation and Parham cyclization as key steps, the first strategy for the synthesis of 14-hydroxy-13a-methylphenanthroindolizidine alkaloids was developed. The route is practical (six steps in 30 % overall yield) and adaptable for all stereoisomers. In addition, we demonstrate for the first time that the structure of hypoestestatin 2 was misassigned.

4-Alkyl-2-trichloromethyloxazolidin-5-ones: Valuable precursors to enantiomerically pure C- and N-protected α-alkyl prolines

Wang, Harry,Germanas, Juris P.

, p. 33 - 36 (1999)

An efficient, economical and enantioselective method for preparation of various mono-and diprotected α-substituted proline derivatives is described. The lithium enolate of known 2-trichloromethyloxazolidin-5-one 3b reacted with electrophiles to furnish th

Design and stereoselective synthesis of ProM-2: A spirocyclic diproline mimetic with polyproline type II (PPII) helix conformation

Reuter, Cédric,Opitz, Robert,Soicke, Arne,Dohmen, Stephan,Barone, Matthias,Chiha, Slim,Klein, Marco Tobias,Neud?rfl, J?rg-Martin,Kühne, Ronald,Schmalz, Hans-Günther

, p. 8464 - 8470 (2015)

With the aim of developing polyproline type II helix (PPII) secondary-structure mimetics for the modulation of prolin-rich-mediated protein-protein interactions, the novel diproline mimetic ProM-2 was designed by bridging the two pyrrolidine rings of a diproline (Pro-Pro) unit through a Z-vinylidene moiety. This scaffold, which closely resembles a section of a PPII helix, was then stereoselectively synthesized by exploiting a ruthenium-catalyzed ring-closing metathesis (RCM) as a late key step. The required vinylproline building blocks, that is, (R)-N-Boc-2-vinylproline (Boc=tert-butyloxycarbonyl) and (S,S)-5-vinylproline-tert-butyl ester, were prepared on a gram scale as pure stereoisomers. The difficult peptide coupling of the sterically demanding building blocks was achieved in good yield and without epimerization by using 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU)/N,N-diisopropylethylamine (DIPEA). The RCM proceeded smoothly in the presence of the Grubbs II catalyst. Stereostructural assignments for several intermediates were secured by X-ray crystallography. As a proof of concept, it was shown that certain peptides containing ProM-2 exhibited improved (canonical) binding towards the Ena/VASP homology 1 (EVH1) domain as a relevant protein interaction target.

A Designed Approach to Enantiodivergent Enamine Catalysis

Macharia, Juliet,Wambua, Victor,Hong, Yun,Harris, Lawrence,Hirschi, Jennifer S.,Evans, Gary B.,Vetticatt, Mathew J.

, p. 8756 - 8760 (2017)

The rational design and implementation of enantiodivergent enamine catalysis is reported. A simple secondary amine catalyst, 2-methyl-l-proline, and its tetrabutylammonium salt function as an enantiodivergent catalyst pair delivering the enantiomers of α-functionalized aldehyde products in excellent enantioselectivities. This novel concept of designed enantiodivergence is applied to the enantioselective α-amination, aldol, and α-aminoxylation/α-hydroxyamination reactions of aldehydes.
