Mathematical Stereochemistry

open access: yes, 2015
Chirality and stereogenicity are closely related concepts and their differentiation and description is still a challenge in chemoinformatics. A new stereoisogram approach, developed by the author, is introduced in this book, providing a theoretical ...

Stereochemistry-Guided DNA Probe for Single Nucleotide Polymorphisms Analysis

open access: yes, 2016
Single nucleotide polymorphisms (SNPs) are the most abundant genetic polymorphisms and are responsible for many genetic diseases and cancers. In general, SNPs detection is performed by a single probe system (SPS), in which a single probe specifically ...

Complete Relative Stereochemistry of Maitotoxin

open access: yes, 2016
By addressing the relative stereochemistry of the four acyclic portions via organic synthesis, the complete relative stereochemistry of maitotoxin (MTX) has been established as 1B. The relative stereochemistry of the C.1−C.15 portion was elucidated via a

Ortho‐Quinone Methide Driven Synthesis of New O,N‐ or N,N‐Heterocycles

open access: yesChemistryOpen, 2019
To synthesize functionalized Mannich bases that can serve two different types of ortho‐quinone methide (o‐QM) intermediates, 2‐naphthol and 6‐hydroxyquinoline were reacted with salicylic aldehyde in the presence of morpholine.
