For imipramine, desipramine, and eight analogs of these well-known drugs, an N-5-aminoalkyl substitution was a minimum but insufficient structural feature associated with chloroquine resistance reversal. Although a second distal aliphatic nitrogen atom was unnecessary for resistance reversal, the direction of the dipole moment vector was critical.

Charge-compensated zinc metallocenes of types [(η(3)-C(2)B(9)H(10))(2)Zn][(η(1)-NMe(2))ZnEt](2) (5) and [{η(3)-(Me)C(2)B(9)H(9)}(2)Zn][(η(1)-NMe(2))ZnEt](2) (6) were produced by reacting σ-/π-chelating aminoalkyl dicarbollides, 7-Me(2)N(H)CH(2)-7,8-C(2)B(9)H(11) (1) and 7-Me(2)N(H)CH(2)-8-Me-7,8-C(2)B(9)H(10) (2), with diethylzinc. Zincocene 5 proved to be an excellent synthon for the formation...

A series of mono-amide-functionalized pillar[5]arenes with different lengths of N-ω-aminoalkyl groups as the side chain on the rim were designed and synthesized, which all formed pseudo[1]rotaxanes in the crystal state. And these pseudo[1]rotaxanes could be transformed into [1]rotaxanes or open forms in the crystal state. In addition, they were also studied in solution by (1)H NMR spectroscopy.

The synthesis of an oligonucleotide functionalized to attach two different reporter groups at specific internucleotide linkages is described. To incorporate the amine specific reporter group the internucleotide linkage is modified to phosphoramidate (N-1-aminoalkyl) and for a thiol specific reporter group the internucleotide linkage is modified to a phosphorothioate diester. The synthetic cycle...

A photocatalytic method for the α-selective hydroaminoalkylation of cinnamate esters has been developed. The reaction involves regioselective addition α-aminoalkyl radicals generated from aniline derivatives or aliphatic amines to α-position unsaturated esters. scope aromatic alkenes was extended styrenes undergoing with anti-Markovnikov selectivity, which confirms importance group at β-positio...

The extent to which deuterium can act as a protecting group to prevent unwanted 1,5-hydrogen atom transfer to aryl and vinyl radical intermediates was examined in the context of the generation of α-aminoalkyl radicals in a pyrrolidine ring. Intra- and intermolecular radical trapping following hydrogen atom transfer provides an illustration of the use of the primary kinetic isotope effect in dir...

This study demonstrates the first enantioselective synthesis of hydroxyalkyl- and aminoalkyl-substituted imidazoles, oxazoles, and thiazoles. The approach developed utilizes a highly effective one-pot reaction cascade that consists of either an organocatalytic epoxidation or aziridination of α,β-unsaturated aldehydes coupled with a [3+2]-annulation, in which amidines, ureas, or thioureas act as...
