Synthetic Biology Approaches to Hydrocarbon Biosensors: A Review
Frontiers in Bioengineering and Biotechnology, 2022 Monooxygenases are a class of enzymes that facilitate the bacterial degradation of alkanes and alkenes. The regulatory components associated with monooxygenases are nature’s own hydrocarbon sensors, and once functionally characterised, these components ...

A mild and effective method for the conversion of alkenes into alcohols in subcritical water [PDF]
Journal of the Serbian Chemical Society, 2007 Alkenes were oxidized to alcohols in subcritical water. A number of alkenes were oxidized directly to their alcohols in excellent yields. The syntheses were performed in 215 cm3 stainless steel high pressure reactor at 120 ºC in 150 cm3 water. The yields

Beilstein Journal of Organic Chemistry, 2013 A “stop-and-flow” strategy was developed for the chemoselective dioxygenation of alkenes with a PIFA-initiated cyclization. This method is conceived for the desymmetrization of seco-diene, and a series of substituted 5-hydroxymethyl-γ-lactones were ...

Photoelectrocatalytic Diazidation of Olefins via Synergistic Dual Iron Species. [PDF]
Adv Sci (Weinh)We report a simple and general approach for 1,2‐diazidation of alkenes by a photoelectrochemical strategy using TMSN3 as an azide source. This transformation proceeds using earth‐abundant iron under mild reaction conditions. It displays broad functional group compatibility and accommodates diverse alkene types‐including unactivated, activated, electron‐

Microbiology Spectrum, 2023 There is a growing need for biological and chemical methods for upcycling plastic waste streams. Pyrolysis processes can accelerate plastic depolymerization by breaking polyethylene into smaller alkene components which may be more biodegradable than the ...

Anomeric Amide‐Enabled Alkene‐Arene and Alkene‐Alkene Aminative Coupling
Angewandte Chemie International EditionAbstractDespite the prominence of C−N bond forming cross‐coupling reactions as a strategy to assemble molecular fragments, aminative coupling approaches, in which two fragments are assembled directly at the heteroatom, represents a rarely exploited retrosynthetic strategy. Herein, we report the design, synthesis, and implementation of an anomeric amide

Radical-Mediated Trifunctionalization Reactions
MoleculesSynthetic radicals have intrinsic power for cascading and multifunctional reactions to construct diverse molecular scaffolds. In the previous review series, we covered 1,2-difunctionalizations, remote 1,3-, 1,4-, 1,5-, 1,6-, and 1,7-difunctionalizations,

Effect of terahertz irradiation on DNA damage repair in living cells
FEBS Open Bio, EarlyView.We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.
