Catalytic approaches towards heterocyclic aziridine and aryl ethylamine scaffolds [PDF]

open access: yes
Nitrogen-containing heterocyclic scaffolds are prevalent within bioactive molecules and natural products. Of these, aziridine scaffolds represent viable targets, both as bioactive molecules (e.g., as covalent inhibitors) but also as synthetic ...

A New Self-Polymerization of Acrylic Acid with a Mono-aziridine Containing Compound

open access: yes, 2013
A new self-polymerization took place between acrylic acid (AA) and a mono-aziridine containing compound, e.g. methyl 3-(aziridin-1-yl) propanoate (MAP) upon mixing that resulted in formation of a linear polyethyleneimine (PEI) with amino-ester bonds ...

2-[3-(Aziridin-1-yl)-2-hydroxypropyl]-5,5-dimethyl-2,5-dihydro-4H-benzo[e]isoindol-4-one (Cytotoxic Oxonaphthalene-Pyrroles, Part III)

open access: yesMolbank, 2012
An hydroxypropyl-aziridine-containing side chain is attached to an oxonaphthalene-annelated pyrrole in expectation of DNA alkylating properties. The cytotoxicity is evaluated against two cell lines, KB-31 and KB-8511, respectively.

Salen–scandium(III) complex-catalyzed asymmetric (3 + 2) annulation of aziridines and aldehydes

open access: yesBeilstein Journal of Organic Chemistry
Oxazolidine is one of the crucial structural moieties of biologically active compounds. A salen–scandium triflate complex-catalyzed asymmetric (3 + 2) annulation of dialkyl 1-sulfonylaziridine-2,2-dicarboxylates and aldehydes generated optically active ...

Metal-free one-pot synthesis of 2-substituted and 2,3-disubstituted morpholines from aziridines

open access: yesBeilstein Journal of Organic Chemistry, 2015
The metal-free synthesis of 2-substituted and 2,3-disubstituted morpholines through a one-pot strategy is described. A simple and inexpensive ammonium persulfate salt enables the reaction of aziridines with halogenated alcohols to proceed via an SN2-type
