Enantiospecific Acid‐Catalysed Hydroperoxidation of Scalemic Tertiary Benzylic Alcohols Facilitating a Concise Asymmetric Synthesis of Yingzhaosu C

European Journal of Organic Chemistry, EarlyView.
Asymmetric synthesis of antimalarial yingzhaosu C was achieved in 4–5 steps by asymmetric Grignard synthesis of (R)‐gossonorol followed by novel enantiospecific hydroperoxidation. We report a concise asymmetric synthesis of antimalarial yingzhaosu C in 59% ee.

Epoxidation of Cashmeran and Unprecedented Rearrangement to an α‐Carbonyl δ‐Spirolactone

European Journal of Organic Chemistry, EarlyView.
A new strategy enables diastereoselective conversion of Cashmeran into a previously unknown α‐carbonyl δ‐spirolactone via epoxidation, Baeyer–Villiger oxidation, and acid‐catalyzed rearrangement. Structure and mechanism were confirmed by NMR, single crystal X‐ray diffraction, and computational studies. We report the epoxidation of Cashmeran followed by

Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

European Journal of Organic Chemistry, EarlyView.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.

Non-photochemical quenching of fluorescence in cyanobacteria

Biochemistry (Moscow), 2007
The pathways of energy dissipation of excessive absorbed energy in cyanobacteria in comparison with that in higher plants are discussed. Two mechanisms of non-photochemical quenching in cyanobacteria are described. In one case this quenching occurs as light-induced decrease of the fluorescence yield of long-wavelength chlorophylls of the photosystem I ...
