A practical method for the chemo- and diastereoselective allylation of α,β-epoxy ketones has been developed by using the convenient air and moisture stable reagent potassium allyltrifluoroborate. Indium metal was found to promote addition in stoichiometric or catalytic amounts, to afford α,β-epoxyhomoallylic tertiary alcohols in high yields and diastereoselectivities, without competing ring-scission of the epoxide.

A range of styrenes and benzaldehydes were smoothly combined to form α,β-epoxy ketones under the synergistic actions of photocatalyst Ru(bpy)3Cl2, tert-butyl hydroperoxide (t-BuOOH), cesium carbonat...
The α-alkylation of ketones and their derivatives by the addition of their corresponding enolates to alkyl halides is a fundamental synthetic transformation, but its utility is limited because the ke...
The total synthesis of 7,10-epimer of the proposed structure of amphidinolide N was accomplished. The requisite chiral C17-C29 subunit was assembled stereoselectively via Keck allylation, Shi epoxid...
Workers manufacturing indium-tin oxide (ITO) are at risk of elevated indium concentration in blood and indium lung disease, but relationships between respirable indium exposures and biomarkers of expo...
An efficient tandem Au(i)/TsOH-catalyzed reaction of enaminones with diazo compounds for the synthesis of pyrroloquinolinone derivatives under mild reaction conditions has been developed. This methodo...
Background: - Some breast cancer cells have specific proteins (receptors) on their surface that make the tumor grow faster than normal cells. One of these receptors is called HER2...
RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase I trial ...
This is a clinical trial of a drug called CMD-193 which is a humanised monoclonal antibody linked to a toxin (calicheamicin). The purpose of this study is to determine in patients with ad...
The purpose of this clinical trial is to describe the toxicity, biodistribution, pharmacokinetics and tumour uptake of a single infusion of ch806 (tagged with a trace amount of radioactive...
Intraoperative tumor localization and resection can be enhanced using intraoperative fluorescence imaging and radiodetection. Girentuximab specifically recognizes carbonic anhydrase IX ex...
Unstable isotopes of indium that decay or disintegrate emitting radiation. In atoms with atomic weights 106-112, 113m, 114, and 116-124 are radioactive indium isotopes.
Organic compounds containing an epoxide group and characterized by strength and thermosetting properties. Epoxy resins are often used as dental materials.
A genus of gram-negative, curved or straight rod-shaped bacteria, in the family ALTEROMONADACEAE. They are chemo-organotrophic, halophilic, and associated with cold marine habitats.
Treatment modality for DENTAL CARIES that uses manual excavation method and GLASS IONOMER CEMENTS. Because of its noninvasiveness and no need for expensive equipment and anesthesia it is promoted as an approach in places where dental care is not readily available.
