being unaffected by various common functional groups, such as alkenes, alkynes, secondary amines, ketones, esters, amides, carboxylic acids, pyridines, nitriles, and nitro compounds. The overall transformation represents a synthetically valuable approach to aldimines from nitriles and can be performed in a sequential one-pot manner, tolerating ester, lactone, carboxamide and unactivated alkene functionalities

An effective and safe new procedure is developed for hyperbranched structure synthesis by stepwise growth using N-(2-chloroethyl)-benzaldimine as a monomer; the effects of the branched structure on the adsorption performance of the fiber have been investigated.

Transformation of <i>trans</i>-4-Aryl-3-chloro-1-(2-chloroethyl)azetidin-2-ones into 3-Aryl-2-(ethylamino)propan-1-ols via Intermediate 1-(1-Aryl-2-chloro-3-hydroxypropyl)aziridines and <i>trans</i>-2-Aryl-3-(hydroxymethyl)aziridines

trans-4-Aryl-3-chloro-1-(2-chloroethyl)azetidin-2-ones, prepared through cyclocondensation of chloroketene and the appropriate imines in a diastereoselective way, were unexpectedly transformed into 3-aryl-2-(ethylamino)propan-1-ols using LiAlH4 in THF under reflux. A stepwise analysis showed that the initially formed 1-(1-aryl-2-chloro-3-hydroxypropyl)aziridines were converted into trans-2-aryl-3-(hydroxymethyl)aziridines, most probably via N-spiro bis-aziridinium intermediates, which were subsequently prone to undergo ring opening by LiAlH4 to afford 3-aryl-2-(ethylamino)propan-1-ols.
