Role of Reversible Dimerization in Reactions of Amphoteric Aziridine Aldehydes
Unprotected aziridine aldehydes belong to the amphoteric class of molecules by virtue of their dual nucleophilicity/electrophilicity. The dimeric nature of these molecules, brought together by a weak and reversible aminal “connection”, was found to be an

Small Nitrogen Heterocycles Containing 1,2,3-Triazoles in the Side Chain
New libraries of aziridine and azetidine derivatives containing 1,4-disubstituted 1,2,3-triazole in the side chain as well as aziridine derivatives containing 1,5-disubstituted 1,2,3-triazole in the side chain were synthesized by transition metals ...

Synthetic Applications of N-H Aziridine Containing Compounds
Unprotected N-H aziridine aldehydes are surprisingly stable compounds which can undergo reactions in the absence of protecting groups. In total, three different transformations were explored during my Master’s thesis.

A Linchpin Synthesis of 6‑Hydroxyceramides from Aziridine Aldehydes
A chemoselective N-oxidation/Meisenheimer rearrangement protocol was developed to generate vinylaziridine scaffolds from aziridine aldehydes. A subsequent Lewis acid-mediated aziridine ring opening with carboxylic acid nucleophiles followed by N–O bond ...

Secondary 3‐Chloropiperidines: Powerful Alkylating Agents
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

Chemically accurate conformational energies for aziridine-2-carbonitrile
The energy of trans-aziridine-2-carbonitrile relative to cis-aziridine-2-carbonitrile was determined by carrying out extensive ab initio computations.

A Facile Synthesis of Amino Acid Derivatives from Aziridines in Liquid Sulfur Dioxide
In the past decades aziridines have played a role of versatile intermediates and important precursors for the synthesis of nitrogencontaining biologically active compounds. Modification of aziridine cycle leads to formation of agents of different classes,

Ring-Opening Reactions of the N‑4-Nosyl Hough–Richardson Aziridine with Nitrogen Nucleophiles
Dinosylated α-d-glucopyranoside was directly transformed into α-d-altropyranosides via in situ formed N-4-nosyl Hough–Richardson aziridine with nitrogen nucleophiles under mild conditions in fair to excellent yields.
