organic chemistry, reviewThe stereochemistry of organic ions in the gas phase can be regarded from two different points of view: (i) in ion formation and (ii) stereospecifity of ion fragmentations. Fast ionization by electron or photon impact shows little stereoselection. Differences in the ...
Research03 Jan 2025 Nature Chemistry P: 1-10 Carbene-catalyzed chirality-controlled site-selective acylation of saccharides The site-selective acylation of saccharides without extensive pre-protection of alcohol units has been a longstanding objective in organic synthesis. Here, the authors demonstrate...
Stereochemistry refers to the study of the three-dimensional aspects of chemistry, particularly in organic compounds. It is a fundamental perspective that is essential for understanding chemical structure and function. AI generated definition based on:Encyclopedia of Physical Science and Technology (Third ...

Axially chiral allenes are important building blocks in organic chemistry due to their potential for functionalization, which can be enhanced by the presence of a synthetically flexible organoboron group. Here, the authors report a stereospecific synthesis of axially chiral alpha-boryl-homoallenyl boroni...
