Monoalkylation of primary amines and N-sulfinylamides.
An efficient monoalkylation of primary amines with primary or secondary alcohols catalyzed by Ra-Ni under mild conditions is described.
متن کاملSynthesis of boron-containing primary amines.
In this study, boron-containing primary amines were synthesized for use as building blocks in the study of peptoids. In the first step, Gabriel synthesis conditions were modified to enable the construction of seven different aminomethylphenyl boronate esters in good to excellent yields. These compounds were further utilized to build peptoid analogs via an Ugi four-component reaction (Ugi-4CR) u...
متن کاملPhotometric Microdetermination of Human Gamma
The main purpose in performing the detailed experimental studies in Part I is the application of the photometric method to the determination of the gamma globulin content of human sera. These experimental studies show that protein fractions such as albumin or alpha globulins, whose electrophoretic mobilities are far removed from gamma globulin, cause little interference with its determination. ...
متن کاملMicrodetermination of Proline in Serum.
An accurate method for determination of proline in serum has been adapted to a micro scale, with good results. Acidic ethanol is used as a serum deproteinizing agent prior to development of color with ninhydrin and its extraction into benzene. The range of accuracy is ± 3.0% with as little as 0.2 ml. serum. The microdetermination of this amino acid facilitates study of the intermediary metaboli...
متن کاملProtecting-group-free synthesis of amines: synthesis of primary amines from aldehydes via reductive amination.
New methodology for the protecting-group-free synthesis of primary amines is presented. By optimizing the metal hydride/ammonia mediated reductive amination of aldehydes and hemiacetals, primary amines were selectively prepared with no or minimal formation of the usual secondary and tertiary amine byproduct. The methodology was performed on a range of functionalized aldehyde substrates, includi...
