Evans, P. Andrew; Oliver, Samuel published the artcile< Regio- and Enantiospecific Rhodium-Catalyzed Allylic Substitution with an Acyl Anion Equivalent>, Recommanded Product: 3-Bromo-5-methylbenzaldehyde, the main research area is chiral nonracemic tertiary allylic alc cyanohydrin pronucleophile allylic substitution; acyclic quaternary substituted aryl ketone stereoselective rhodium catalyzed preparation; cyanohydrin acyl anion equivalent stereoselective allylic alkylation pronucleophile.

The construction of enantiomerically enriched acyclic quaternary substituted ketones via the regio- and enantiospecific rhodium-catalyzed allylic alkylation reaction of chiral nonracemic tertiary allylic alcs. with cyanohydrin pronucleophiles is described. This approach provides an alternative method to the α-arylation and vinylation of acyclic disubstituted ketone enolates, which remains a challenging endeavor. The combination of the allylic alkylation with ring-closing metathesis facilitates the preparation of enantiomerically enriched 2,2-disubstituted naphthalene-1-ones, which have proven very difficult to prepare using a more conventional dearomatization strategy.

Organic Letters published new progress about Allylic alkylation catalysts, stereoselective. 188813-04-9 belongs to class bromides-buliding-blocks, and the molecular formula is C8H7BrO, Recommanded Product: 3-Bromo-5-methylbenzaldehyde.

Deng, Yong;Wang, Xiang;Liu, Yongtian;Xu, Yao;Zhang, Jing;Huang, Fei;Li, Bing;Miao, Yuqing;Sun, Yun;Li, Yuhao research published 《 Dual-light triggered metabolizable nano-micelles for selective tumor-targeted photodynamic/hyperthermia therapy》, the research content is summarized as follows. Phototherapy, including photodynamic and photothermal therapies, is a non-invasive photo-triggered tumor treatment. Combination therapy and new synergistic therapeutic reagents may hold promise for improving these treatments. Herein, we report an amphiphilic iridium-based photosensitizer (C14-IP2000) loaded with a hydrophobic photo-thermal drug (ZnPc) to form nano-micelles (ZNPs) for dual-light triggered tumor phototherapy. The C14-IP2000 was contained within ZNPs consisting of an iridium complex core decorated with hydrophilic polyethylene glycol chains to extend the time in blood circulation, and two hydrophobic carbon chains to enhance the loading capacity and the hydrophobic interaction with the loaded reagent. The designed ZNPs showed effective blood circulation, passive tumor targeting ability, remarkable photodynamic conversion ability, and good photothermal conversion capability, and therefore may be used for combined tumor ablation. Our results demonstrated that the amphipathic bionic structure of ZNPs not only enables self-assembled reagent fabrication with prolonged circulation time and favorable metabolic characteristics for tumor combination therapy, but also provides a nanostructure strategy for the modification of functionalized reagents.
