Progress of Enantioselective Nitrile Biotransformations in Organic Synthesis

open access: yesCHIMIA, 2009
Recent progress of enantioselective biotransformations of nitriles including various functionalized nitriles, ?-hydroxy and ?-amino nitriles, oxirane- and aziridine-containing carbonitriles is summarized in this short review article.

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

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.

Secondary 3‐Chloropiperidines: Powerful Alkylating Agents

open access: yesChemistryOpen
In previous works, we demonstrated that tertiary 3‐chloropiperidines are potent chemotherapeutics, alkylating the DNA through the formation of bicyclic aziridinium ions. Herein, we report the synthesis of novel secondary 3‐chloropiperidine analogues. The

Nitrene Transfer Catalyzed by a Non-Heme Iron Enzyme and Enhanced by Non-Native Small-Molecule Ligands [PDF]

open access: yes, 2019
Transition-metal catalysis is a powerful tool for the construction of chemical bonds. Here we show that Pseudomonas savastanoi ethylene-forming enzyme, a non-heme iron enzyme, can catalyze olefin aziridination and nitrene C–H insertion, and that these ...
