Synthesis of N-Z, N′-Formyl α-Amino Acid Derived Gem-Diamines [PDF]

open access: yes, 2008
A variety of N-carbobenzoxy, N′-formyl gem-diaminoalkyl derivatives have been obtained through Goldsmith-Wick reaction of Z-α-amino acid/peptide acid derived isocyanates with 96% HCOOH in presence of 4-dimethylaminopyridine (DMAP) as catalyst.

2-((Diphenylmethylene)amino)ethyl N-(Cyclohexyl)carbamate

open access: yesMolbank
Lipid-like nanoparticles (LLNPs) have been shown to be an effective encapsulation and delivery tool for therapeutic molecules. While the preclinical development of lipid nanoparticle formulations has been of paramount importance, next-generation LLNPs ...

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 ...

Rearrangement Inequalities on the Lattice Graph [PDF]

open access: yesarXiv, 2022
The Polya-Szeg\H{o} inequality in $\mathbb{R}^n$ states that, given a non-negative function $f:\mathbb{R}^{n} \rightarrow \mathbb{R}_{}$, its spherically symmetric decreasing rearrangement $f^*:\mathbb{R}^{n} \rightarrow \mathbb{R}_{}$ is `smoother' in the sense of $\| \nabla f^*\|_{L^p} \leq \| \nabla f\|_{L^p}$ for all $1 \leq p \leq \infty$.
