Evolved P450 mutants as general oxidation catalysts for target synthesis via C–H activation [PDF]

open access: yes, 2022
This thesis describes synthetic studies towards three natural product precursors: the tricyclic core of the abietane diterpenoids, a bicyclic lactone intermediate on Danishefsky’s route towards eleutherobin, and the hydrocarbon core of Taxol®.

A Novel Superabsorbent Polymer from Crosslinked Carboxymethyl Tragacanth Gum with Glutaraldehyde: Synthesis, Characterization, and Swelling Properties

open access: yesInternational Journal of Biomaterials, 2021
Nowadays, current global environmental problems include measures to eliminate or reduce the negative impact of chemicals from petroleum sources and, therefore, the use of materials from natural resources is increasingly recommended.

1,1′-{[3,5-Bis(dodecyloxycarbonyl)-4-(naphthalen-2-yl)-1,4-dihydropyridine-2,6-diyl]bis(methylene)}bis{4-[(E)-2-(naphthalen-2-yl)vinyl]pyridin-1-ium}dibromide

open access: yesMolbank, 2022
Synthesis of a double-charged cationic amphiphilic 1,4-dihydropyridine derivative with dodecyl ester groups at positions 3 and 5 of the 1,4-DHP ring was performed starting from Hantzsch type cyclization of dodecyl acetoacetate, 2-naphthaldehyde and ...

Studies towards the total synthesis of heteroclitin F and taiwanschirin A, B, C, and D [PDF]

open access: yes, 2021
This thesis initially describes model studies developed towards key structural fragments of the taiwanschirin family of natural products. Through the use of these models, an original approach was conceived to enable the installation of the (Z)–enone as a

Effectiveness of pharmacist home visits for individuals at risk of medication-related problems: a systematic review and meta-analysis of randomised controlled trials

open access: yesBMC Health Services Research, 2020
Background Medication mismanagement is a major cause of both hospital admission and nursing home placement of frail older adults. Medication reviews by community pharmacists aim to maximise therapeutic benefit but also minimise harm.

Memory of chirality: An emerging strategy for asymmetric synthesis

open access: yes, 2004
'Memory of chirality' (MOC) is an intriguing strategy for asymmetric synthesis because it appears to do the impossible: the sole chiral center of a molecule directs the stereochemical course of a reaction even though that center is destroyed in

Progress, Positivism, and Scientific Revolution: The Synthesis of Darwin's Theory of Evolution [PDF]

open access: yes
Bridging the rift between the sciences and the humanities is important for fostering creativity in all fields of study. Many scientific theories, especially those producing the most profound impact on our understanding of the world, are a continuity of ...

On‐Surface Synthesis [PDF]

open access: yesChemPhysChem, 2019
On‐surface synthesis represents a chemical approach whereby molecular building blocks holding adequate functional groups are dosed onto surfaces that support or even drive their covalent linkage. The new environment created by the surface confinement and the frequent lack of solvents (most commonly being performed under vacuum conditions) makes this ...
