چکیده

In the presence of a Brønsted acid catalyst, both aldehydes and N-Boc-aminals were converted to enecarbamates and N-Boc-iminium salts as activated nucleophiles and electrophiles, respectively, giving unprecedented Mannich adducts. The asymmetric variant of the present Mannich reaction has also been demonstrated with a chiral phosphoric acid catalyst.

An enantioselective Brønsted acid catalyzed enamine Mannich reaction.

An enantioselective Brønsted acid catalyzed Mannich reaction between acetophenone derived enamines and N-Boc imines has been developed. Simple diol (S)-H(8)-BINOL has been identified as the optimal catalyst, to afford versatile beta-amino aryl ketones in good yield and enantiomeric excess.

Asymmetric synthesis of syn-propargylamines and unsaturated β-amino acids under Brønsted base catalysis

Propargylamines are important intermediates for the synthesis of polyfunctional amino derivatives and natural products and biologically active compounds. The classic method of synthesizing chiral propargylamines involves the asymmetric alkynylation of imines. Here, we report a significant advance in the catalytic asymmetric Mannich-type synthesis of propargylamines through catalytic asymmetric ...

A facile direct anti-selective catalytic asymmetric Mannich reaction of aldehydes with preformed N-Boc and N-Cbz imines.

Anti-selective Mannich reactions of N-Boc and N-Cbz protected imines with unmodified aldehydes proceeded smoothly under the catalysis of a secondary amine-thiourea catalyst, which led to high yields (70%-95%) and excellent enantioselectivity (up to 96 : 4 dr and >99% ee) under conventional organic synthetic operations.

Highly enantio- and diastereoselective Mannich reactions of glycine Schiff bases with in situ generated N-Boc-imines catalyzed by a cinchona alkaloid thiourea.

Highly enantio- and diastereoselective organocatalytic Mannich reactions of glycine Schiff bases with N-Boc-protected imines are described. Imines were generated in situ from bench-stable alpha-amido sulfones. Catalysis mediated by a cinchona alkaloid thiourea provided optically active alpha,beta-diamino acid derivatives with up to 99% ee and near-perfect diastereoselection.

Highly efficient asymmetric anti-Mannich reactions of carbonyl compounds with N-carbamoyl imines catalyzed by amino-thiourea organocatalysts.

A series of pyrrolidine-based organocatalysts which bear three synergistic features, i.e. secondary amino group, various H-bond donor groups at the 4-position and a stereocontrol silyl ether group at the α-position of the pyrrolidine nitrogen atom, were developed. They were screened in anti-Mannich reactions of carbonyl compounds with preformed or in situ generated N-protected α-imino ethylglyo...
