This work describes Ni-catalyzed cross-electrophile coupling of benzyl chloroformate derivatives with aryl iodides that generates a wide range of diaryl methane products. The mild reaction conditions merit the C–O bond radical fragmentation of benzyl chloroformates via halide abstraction or a single electron reduction by a Ni catalyst. This work offers a new substrate type for cross-electrophile couplings
这项工作描述了镍催化的氯甲酸苄酯衍生物与芳基碘化物的交叉亲电子偶联,生成多种二芳基甲烷产物。温和的反应条件使得氯甲酸苄酯的 C-O 键自由基通过卤化物夺取或 Ni 催化剂的单电子还原而断裂。这项工作为交叉亲电子偶联提供了一种新的底物类型。
Novel Indanone Derivatives as Potential Imaging Probes for β-Amyloid Plaques in the Brain
Amyloid senile plaqueprobes: A series of indanone derivatives has been synthesized and characterized. In vitro binding studies, staining of Alzheimer's disease (AD) brain sections, autoradiography, and biodistribution data all suggested that the indanone derivatives might represent potential amyloid imaging agents for the detection of senile plaques in AD.

Disclosed herein are methods for preparing tertiary alcohols from an optionally substituted phenyl ketone or an optionally substituted pyridinyl ketone that includes the use of a chiral ligand and boron trifluoride diethyl etherate. Tertiary alcohols can be used to prepare synthetic versions of natural products and/or pharmaceuticals.
