Expedient Protocol for Solid-Phase Synthesis of Secondary and Tertiary Amines
摘要:
An expedient solid-phase synthetic approach to secondary and tertiary amines was developed. The protocol employs conversion of resin-bound amino alcohols to the corresponding iodides, followed by iodide displacement with primary or secondary amines or with unprotected amino alcohols, This two-step procedure, affording products in good to excellent yields, is suitable for solid-phase synthesis of polyamines.

To provide an electret having high stability with time and thermal stability of retained electric charge and having excellent charge retention performance, and an electrostatic induction conversion device comprising such an electret.
An electret obtained from a composition comprising a compound (A) having a molecular weight of from 50 to 2000 and having at least two polar functional groups, and a polymer (B) having a number average molecular weight of more than 2000 and having reactive functional groups reactive with the above polar functional groups. An electrostatic induction conversion device comprising such an electret.
This invention relates to crosslinked amine-containing polymers for binding compounds or ions, and more specifically relates to pharmaceutically acceptable compositions for binding compounds or ions that include crosslinked amine-containing polymers. The pharmaceutically acceptable composition includes, for example, crosslinked polyamine particles, or pharmaceutically acceptable salts thereof, having a particle size distribution wherein greater than 10 vol. % of the particles have a particle size greater than 500 μm.
