Paragraph 0081; 0083; 0084, (2015/11/23)
The invention discloses a separation matrix which comprises a plurality of separation ligands, defined by the formula R1-L1-N(R3)-L2-R, immobilized on a support, wherein R1 is a five- or six-membered, substituted or non-substituted ring structure or a hydroxyethyl or hydroxypropyl group; L1 is either a methylene group or a covalent bond; R2 is a five- or six-membered, substituted or non-substituted ring structure; L2 is either a methylene group or a covalent bond; R3 is a methyl group; and wherein if R1 is a hydroxyethyl group and L1 is a covalent bond, R2 is a substituted aromatic ring structure or a substituted or non-substituted aliphatic ring structure.

The homogeneously catalyzed hydrogenation of 1,3-oxazolidines affording unsymmetrically substituted 2-N-(dialkylamino)ethanols is reported showing for the first time that Rh(I) catalysts based on chelating diphosphines can be advantageous for this reaction.

N-Phenyl- and N-alkyl-oxazolidines react with alkyl chlorosilanes in the presence of electron rich aromatic compounds with the formation of the expected Mannich bases: 2-methoxycarbonyl-3-methyloxazolidine also reacts with 2-methylfuran in the presence of thionyl chloride to give an a-amino acid derivative: the iminium salt derived from 1,3-dimethylimidazolidine was also shown to react with 2-methylfuran.

Fairhurst, Robin A.,Heaney, Harry,Papageorgiou, George,Wilkins, Robert F.,Eyley, Stephen C.
, p. 1433 - 1436 (2007/10/02)
3-Methyl-1,3-oxazolidine and 3,4-dimethyl-5-phenyloxazolidine react with acidic reagents under aprotic conditions to afford reactive intermediates that interact with nucleophilic aromatic substrates and enolsilyl ethers to afford good yields of Mannich bases.
