Tyrosine-Derived Novel Benzoxazine Active in a Rat Syngenic Mammary Tumor Model of Breast Cancer

In continuing efforts of improving benzoxazepine derivatives as an anti-breast cancer agent, a new chemical entity, benzoxazine, was designed from scaffold morphing. Structure-activity relationship studies revealed that H, -OMe, -CF3, and -F were well tol

Carbonylative Coupling of Alkyl Zinc Reagents with Benzyl Bromides Catalyzed by a Nickel/NN2 Pincer Ligand Complex

An efficient catalytic protocol for the three-component assembly of benzyl bromides, carbon monoxide, and alkyl zinc reagents to give benzyl alkyl ketones is described, and represents the first nickel-catalyzed carbonylative coupling of two sp3-carbon fragments. The method, which relies on the application of nickel complexed with an NN2-type pincer ligand and a controlled release of CO gas from a solid precursor, works well with a range of benzylic bromides. Mechanistic studies suggest the intermediacy of carbon-centered radicals.

Exploiting the 4-Phenylquinazoline Scaffold for the Development of High Affinity Fluorescent Probes for the Translocator Protein (TSPO)

The quinazoline class was exploited to search for a new translocator protein (TSPO) fluorescent probe endowed with improved affinity and residence time (RT). Computational studies on an "in-house" collection of quinazoline derivatives, featuring highly st

A scalable process for the synthesis of (E)-pterostilbene involving aqueous Wittig olefination chemistry

A synthetic approach toward the pharmacologically active (E)-stilbene pterostilbene is described using a Wittig reaction conducted under mildly basic, aqueous conditions. A surprising, non-intuitive difference in (E)/(Z) stereoselectivity was observed comparing the two possible isomeric Wittig routes, allowing for the development of a highly efficient process to access the title stilbene derivative through a one-pot olefination deprotection sequence.

Total synthesis of naturally occurring furan compounds 5-{[(4- hydroxybenzyl)oxy]methyl}-2-furaldehyde and pichiafuran C

The synthesis of the natural furan derivatives 5-{[(4-hydroxybenzyl)oxy] methyl}-2-furaldehyde and pichiafuran C is described. Diverse alternative synthetic approaches were developed for the preparation of these natural products. They were prepared through an etherification reaction of the key furan precursor 5-(hydroxymethyl)-2-furaldehyde (HMF), which can be readily obtained from d-fructose, d-glucose, or sucrose, with the corresponding alcohols. 5-{[(4-Hydroxybenzyl)oxy]methyl}-2-furaldehyde was not only obtained in a two-step methodology but also by a biomimetic single-step synthesis. Similarly, pichiafuran C was prepared by three different syntheses, each one by a two-step procedure, also including a biomimetic approach. Georg Thieme Verlag Stuttgart.

Natural products-based insecticidal agents 11. Synthesis and insecticidal activity of novel 4α-arylsulfonyloxybenzyloxy-2β- chloropodophyllotoxin derivatives against Mythimna separata Walker in vivo

In continuation of our program aimed at the discovery and development of natural products-based insecticidal agents, 14 novel 4α- arylsulfonyloxybenzyloxy-2β-chloropodophyllotoxin derivatives were stereoselectively semisynthesized from podophyllotoxin, an

Regioselective hydroxylation of phenols by simultaneous photochemical generation of phenol cation-radical and hydroxyl radical

Substituted phenols having pendant isoquinoline N-oxide were synthesized and their photochemical and luminiscent properties studied. Photolysis in an acid medium was found to yield the related photohydroxylation products, in a regioselective process, in a
