The present invention applications for same. More particularly, the present invention relates to novel aziridine aldehydes and processes for preparing these novel compounds. The invention also relates to aziridine-conjugated amino derivatives, and processes for preparing the same. Pentacyclic compounds may be prepared using the aziridine aldehydes of the present invention, and the invention relates to these compounds and the processes by which they are made. The invention also relates to aziridine-conjugated bioactive molecules, such as amino acids and peptides, and processes for preparing such compounds.
Dimeric alpha-aziridine aldehydes have been used as the aldehyde component in Ugi and Passerini reactions. The highly reactive mixed anhydride intermediate is subject to nucleophilic attack by the aziridine, leading to 'homo-Ugi' beta-acylaziridinyl-alpha-amino-amides. The products can be readily transformed into substituted lactones.

functionalized isocyanides in the aziridine aldehyde-driven multicomponent synthesis of piperazinones. High diasteroselectivity for each isocyanide was observed. A theoretical evaluation of the reaction course corroborates the experimental data. Moreover, the reactivity of cis- and trans-configured aziridine aldehyde dimers has been compared. This study further probes the dimer-driven mechanism of
