Polyurethanes by ring‐opening polymerization initiated from alcohol moiety‐tethering acylazide [PDF]

open access: yes
An orthogonal agent having both alcohol and acylazide groups was used to construct novel polyurethanes by a simple synthetic process. Ring-opening polymerization (ROP) of δ-valerolactone from the orthogonal agent afforded a crystalline polymer having ...

Polyfunctional pyrazoles. 9. Synthesis of 1-alkyl(aryl)-3-[4-(hydroxymethyl)-1h-pyrazol-3-yl]ureas [PDF]

open access: yes, 2014
We have developed an effective method for the preparation of 1-alkyl(aryl)-3-[4-(hydroxymethyl)-1Н-pyrazol-3-yl]ureas based on the interaction of 4-hydroxymethylpyrazole-3-carbonyl azides with primary aliphatic and aromatic amines under the conditions of

Synthesis of a mitochondria-targeted spin trap using a novel Parham-type cyclization [PDF]

open access: yes, 2009
A new cyclic nitrone spin trap, [4-(3′,3′-dibutyl-2′-oxy-3′H-isoindol-5′-yloxy)butyl]triphenylphosphonium bromide (MitoSpin), bearing a lipophilic cation has been prepared by a route that involves a novel Parham-type lithiation–cyclization of an ...

The Photodimer from B-Nitrostyrene [PDF]

open access: yes, 1964
Photodimerization of β-nitrostyrene by sunlight or a mercury arc lamp yields l,3-diphenyl-2,4-dinitrocyclobutane (II). Only one stereoisomer was obtained.
