Strain Release Chemistry of Photogenerated Small‐Ring Intermediates [PDF]
Chemistry - A European Journal, 2021 AbstractPhotochemical processes, such as isomerizations and cycloadditions, have proven to be very useful in the construction of highly strained molecular frameworks. Photoinduced ring strain enables subsequent exergonic reactions which do not require the input of additional chemical energy and provides a variety of attractive synthetic options leading

Efficient ring perception for the Chemistry Development Kit [PDF]
Journal of Cheminformatics, 2014 The Chemistry Development Kit (CDK) is an open source Java library for manipulating and processing chemical information. A key aspect in handling chemical structures is the determination of the chemical rings. The rings of a structure are used areas including descriptors, stereochemistry, similarity, screening and atom typing. The CDK includes multiple

Put a ring on it: application of small aliphatic rings in medicinal chemistry
RSC Medicinal Chemistry, 2021 Aliphatic small rings including cyclopropanes, cyclobutanes, oxetanes, azetidines and bicyclo[1.1.1]pentanes have been increasingly exploited in medicinal chemistry. This review summarises judicious successful application and reported limitations of these ring systems.

Catalytic Cascade Reactions Inspired by Polyketide Biosynthesis
CHIMIA, 2020 Aldol reactions belong to the most important methods for carbon–carbon bond formation and are also involved in one of the most astonishing biosynthetic processes: the biosynthesis of polyketides governed by an extraordinarily sophisticated enzymatic ...

Oxetanes: Recent Advances in Synthesis, Reactivity and Medicinal Chemistry [PDF]
, 2016 The 4-membered oxetane ring has been increasingly exploited for its behaviors, i.e. influence on physicochemical properties as a stable motif in medicinal chemistry, and propensity to undergo ring opening reactions as a synthetic intermediate.

A Unified Mechanism on the Formation of Acenes, Helicenes, and Phenacenes in the Gas Phase. [PDF]
, 2020 A unified low-temperature reaction mechanism on the formation of acenes, phenacenes, and helicenes-polycyclic aromatic hydrocarbons (PAHs) that are distinct via the linear, zigzag, and ortho-condensed arrangements of fused benzene rings-is revealed. This
