Spiro- and bridged bicyclic structures are in demand for their sp3-rich frameworks that offer unique physiochemical properties and precisely positioned substituent groups. In order to rapidly access such molecules in a cross-coupling fashion we describe olefin amine (OLA) reagents for the transformation of aldehydes and ketones into all three topological types of bicyclic N-heterocycles: bridged, spiro-, and fused rings. The OLA reagents are easily prepared and allow the synthesis of complex molecular frameworks under operationally simple conditions that tolerate a wide array of functional groups. Investigations into the Mn or Fe promoted reaction pathway support a metal hydride hydrogen atom transfer (MH-HAT) to generate a C-centered radical that undergoes addition to an unactivated imine, leading to an N-centered radical. A catalytic cycle featuring regeneration of the metal catalyst by O2 and a second HAT to form the unprotected saturated N-heterocycle appears to be operative.

This report describes the preparation of some new β-lactam nanocopolymers. These nanoparticles are synthesized in water by emulsion polymerization of an acrylate β-lactam pre-dissolved in a mixture of co-monomers in the presence of sodium dodecyl sulfate as a surfactant and potassium persulfate as a radical initiator. Dynamic light scattering analysis and electron microscopy images of these emulsions show that the nanoparticles are approximately 30-70 nm in diameter. These compounds have been evaluated for their antimalarial activities against chloroquine-resistant Plasmodium faliparum K1 strain demonstrating IC50 varying from 14 to 50 μM. The interactions between these β-lactam nanocopolymers and the P. falciparum single-stranded DNA-binding proteins have been studied by molecular docking calculations.
Nano-tube TiO2 as a new catalyst for eco-friendly synthesis of imines in sunlight
Hosseini-Sarvari, Mona
experimental part, p. 547 - 550 (2012/01/06)
Nanomaterials are considered as suitable heterogeneous catalysts for many organic reactions. Herein nano-tube TiO2 has been reported as a heterogeneous catalyst, for synthesis of imines in sunlight at room temperature under solvent-free conditions. The condensation of less electrophilic carbonyl compounds with poorly nucleophilic amines was afforded imines in excellent yields.

Various 3-(N-alkylamino)-1-propanols were obtained by the lithium aluminum hydride reduction of the products of the reaction of 3-amino-1-propanol with carbonyl compounds.This method for the synthesis of aminopropanols is applicable in the case of optimal electrophilicity of the carbonyl component.
