We present a novel concept for the in situ control of site-selectivity of catalytic acetylations of partially protected sugars using light as external stimulus and oligopeptide catalysts equipped with an azobenzene moiety. The isomerizable azobenzene

Herein, we report the oligopeptide-catalyzed site-selective acylation of partially protected monosaccharides. We identified catalysts that invert site-selectivity compared to N-methylimidazole, whi...

We describe the isolation as well as IR and UV/Vis spectroscopic characterization of (4-methoxyphenyl)phosphine disulfide in argon matrices at 10 K. The title compound proved to be highly photolabile; irradiation with UV light (λ = 334 nm) led to re

Here we report the photochemical reactions of triplet phenylphosphinidene with carbon monoxide and nitric oxide. The photolysis of phenylphosphirane in carbon monoxide-doped matrices enabled the first spectroscopic identification of phenylphosphakete

Carbonothioic O,O-acid (monothiocarbonic acid), the sulfur analogue of carbonic acid, is thus far an experimentally unreported molecule of atmospheric and biochemical relevance. Computations at the CCSD(T)/cc-pVQZ//CCSD(T)/cc-pVTZ level of theory rev

Transformations of 2-formylbenzoic acid provide direct access to a series of heterocyclic organic compounds such as phthalides and isoindolinones. Here, we use (+)-cinchonine as a catalyst in conjunction with nonafluoro-tert-butanol as a hydrogen-bon

Triplet phenylphosphinidene was prepared by light-induced elimination of ethylene from the corresponding phenylphosphirane and was characterized by IR and UV/vis spectroscopy together with matching of its spectral data with density functional theory

Using an adamantane-anchored methylimidazole-containing oligopeptide as catalyst, the first examples for an enantioselective Dakin—West reaction are reported.
