Atom efficient, multicomponent reactions that lead to high-value products from inexpensive starting materials are of both economic and ecological interest for industrial organic synthesis. alpha-Amino acids are amongst the most important compounds in chemistry and biology. As well as their biochemical significance as building blocks of peptides and… (More)
Dihydroxylations of simple alkenes were carried out for the first time in excellent yields and selectivities with molecular oxygen as oxidant [(Eq. (a)]. Both oxygen atoms are used productively and are incorporated into the product in this transition metal catalyzed alkene oxidation.
Primary and unbranched secondary amines are obtained by the highly selective hydroaminomethylation of olefins with ammonia [Eq. (a)]. The selectivity is readily controlled with a new dual Rh/Ir catalyst in a two-phase system.
The Suzuki reaction of aryl bromides is efficiently catalyzed by palladium/ phosphite complexes generated in situ. The influence of ligand, base, and different additives is examined. The process tolerates various functional groups and catalyst turnover numbers up to 820,000 are obtained even with deactivated aryl bromides. For the first time it is shown… (More)
Previous studies based on whole genome sequencing have demonstrated limited genetic diversity within Mycobacterium avium subsp. paratuberculosis (MAP) strains isolated from human hosts . In contrast, animal derived MAP stains are genetically more diverse. In order to understand the possible zoonotic transmission of MAP a robust genotyping platform that… (More)
Mucoceles result from mucus and secretion accumulation inside cavities, such as the paranasal sinuses, when inflammatory, infectious, traumatic or surgical processes obstruct their drainage pathways. A mucocele with infected mucus content is called mucopyocele [1-5]. The slow expansion of the mucusfilled mass compresses the cavity leading to a gradual… (More)
