1212469-34-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1212469-34-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,2,4,6 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1212469-34:
(9*1)+(8*2)+(7*1)+(6*2)+(5*4)+(4*6)+(3*9)+(2*3)+(1*4)=125
125 % 10 = 5
So 1212469-34-5 is a valid CAS Registry Number.

Densely substituted l -proline esters as catalysts for asymmetric michael additions of ketones to nitroalkenes

Ruiz-Olalla, Andrea,Retamosa, María De Gracia,Cossío, Fernando P.

, p. 5588 - 5599 (2015)

Homochiral methyl 4-aminopyrrolidine-2-carboxylates are readily obtained by means of asymmetric (3 + 2) cycloadditions between azomethine ylides and nitroalkenes, followed by catalytic hydrogenation of the intermediate 4-nitro cycloadducts. These 4-aminopyrrolidine-2-carboxylate esters belong to the l-series of natural amino acids and catalyze asymmetric Michael additions of ketones to nitroalkenes. However, the enantioselectivity observed with these novel unnatural organocatalysts is opposite to that obtained with l-proline. Since both 4-nitro and 4-amino l-proline esters are efficient organocatalysts of aldol reactions, these results permit to modulate asymmetric quimioselective aldol and conjugate addition reactions.

Sugar-based pyrrolidine as a highly enantioselective organocatalyst for asymmetric michael addition of ketones to nitrostyrenes

Wang, Lei,Liu, Jie,Miao, Tao,Zhou, Wei,Li, Pinhua,Ren, Kai,Zhang, Xiuli

, p. 2571 - 2578 (2010)

A modular sugar-based pyrrolidine (3) was prepared and was found to be a highly enantioselective organocatalyst for the asymmetric Michael addition of ketones to nitrostyrenes. In the presence of 10 mol% of 3, a pyrrolidine unit anchored to a natural D-gl

Pyrrolidine-pyridinium based organocatalysts for highly enantioselective Michael addition of cyclohexanone to nitroalkenes

Xu, Dan-Qian,Wang, Bing-Tao,Luo, Shu-Ping,Yue, Hua-Dong,Wang, Li-Ping,Xu, Zhen-Yuan

, p. 1788 - 1794 (2007)

A novel class of pyrrolidine-pyridinium based organocatalysts has been developed and demonstrated to efficiently catalyze the asymmetric Michael addition reactions of unmodified cyclohexanone to nitroalkenes in the ionic liquid BMImBF4 with up

Comparison of different polymer- and silica-supported 9-amino-9-deoxy-epi-quinines as recyclable organocatalysts

Porta, Riccardo,Coccia, Francesca,Annunziata, Rita,Puglisi, Alessandra

, p. 1490 - 1499 (2015)

9-Amino-9-deoxy-epi-quinine, properly modified by suitable linkers, was anchored on highly cross-linked polystyrene, poly(ethylene glycol), and silica. The resulting species were characterized by NMR spectroscopy and tested as supported organocatalysts in the reaction between isobutyric aldehyde and trans-β-nitrostyrene. Polystyrene- and poly(ethylene glycol)-supported catalysts outperformed their nonsupported counterpart affording the desired product in high yield and ee (>90 % ee). Silica-supported catalysts proved to be less efficient in terms of both chemical yield and enantioselectivity. Polystyrene- and poly(ethylene glycol)-supported 9-amino-9-deoxy-epi-quinine were then used in the same reaction with different substrates, leading to the desired products in high yield and ee, as well as in three other reactions operating with different mechanism. An investigation of the recyclability of the polystyrene- and poly(ethylene glycol)-supported systems showed that these could be recovered and recycled with no loss of stereochemical activity but with a marked erosion of chemical efficiency occurring at the fifth reaction cycle. This was ascribed to chemical degradation of the alkaloid occurring during the reaction.

Chiral Pyrrolidine Bridged Polyhedral Oligomeric Silsesquioxanes as Heterogeneous Catalysts for Asymmetric Michael Additions
