Design of more powerful iron-TAML peroxidase enzyme mimics

(Figure Presented) Environmentally useful, small molecule mimics of the peroxidase enzymes must exhibit very high reactivity in water near neutral pH. Here we describe the design and structural and kinetic characterization of a second generation of iron(I

NEW DIAMINE AND POLYMER USING THE SAME, LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT FILM AND LIQUID CRYSTAL DISPLAY ELEMENT

PROBLEM TO BE SOLVED: To inexpensively provide a liquid crystal aligning agent for obtaining a liquid crystal alignment film which has high liquid crystal aligning properties, can reduce residual DC voltage (RDC), has good electric characteristics such as a voltage holding ratio (VHR) and is hardly scraped. SOLUTION: There is provided a liquid crystal aligning agent which contains a polyamic acid or a derivative thereof using a diamine represented by the following formula (2) as at least one of raw materials. In the formula (2), R is a benzene ring, a naphthalene ring or an anthracene ring; Des is a group detached by heat; and R' is H or Des. The group detached by heat is a t-butylcarbamate group.

An efficient and highly chemoselective N-Boc protection of amines, amino acids, and peptides under heterogeneous conditions

A simple and efficient procedure for chemoselective mono-N-Boc protection of various structurally diverse amines, amino acids, and peptides with di-tert-butyl dicarbonate using Amberlyst-15 as catalyst in ethanol is described. The catalyst can be readily separated from the reaction products with simple filtration and recovered for direct reuse. No competitive side-reactions such as formation of isocyanate, urea, oxazolidinone, and N,N-di-Boc derivatives were observed.

Guanidine hydrochloride as an organocatalyst for N-Boc protection of amino groups

A simple and efficient method for the chemoselective N-Boc protection of the amine moiety in a variety of compounds is described using di-tert-butyl dicarbonate and guanidine hydrochloride as an organocatalyst in ethanol at 35-40°C. Selective mono-N-Boc protection of diamines and chemoselective protection of hydroxylamines without formation of any side products is achieved. Amino acids and peptides are N-Boc protected efficiently in excellent yields under convenient reaction conditions.
