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 ...

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.

Chemical footprints of giant planet formation. Role of planet accretion in shaping the C/O ratio of protoplanetary disks [PDF]
A&A 678, A33 (2023), 2023 Protoplanetary disks, the birthplaces of planets, commonly feature bright rings and dark gaps in both continuum and line emission maps. Accreting planets are interacting with the disk, not only through gravity, but also by changing the local irradiation and elemental abundances, which are essential ingredients for disk chemistry.

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

Conformer-specific Chemistry Imaged in Real Space and Time [PDF]
, 2021 Conformational isomers or conformers of molecules play a decisive role in chemistry and biology. However, experimental methods to investigate chemical reaction dynamics are typically not conformer-sensitive. Here, we report on a gas-phase megaelectronvolt ultrafast electron diffraction investigation of {\alpha}-phellandrene undergoing an electrocyclic ...

On-Surface Synthesis of Silole and Disilacyclooctaene Derivatives [PDF]
, 2023 Sila-cyclic rings are a class of organosilicon cyclic compounds and have abundant application in organic chemistry and materials science. However, it is still challenging to synthesize compounds with sila-cyclic rings in solution chemistry due to their low solubility and high reactivity.

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.
