Amino-Supported Palladium Catalyst for Chemo- and Stereoselective Domino Reactions

A solid amino-supported palladium catalyst is used in an oxidative domino reaction for the diastereoselective construction of alkyne-substituted cyclopentenol compounds. This heterogeneous catalyst exhibits high efficiency and excellent chemoselectivity, as well as good recyclability. The chemoselectivity of the domino reactions was readily controlled by switching the solvent and catalyst. Asymmetric syntheses and an oxidative carbocyclization-borylation reaction have also been developed based on the heterogeneous palladium catalyst.

Copper-Mediated Deacylative Coupling of Ynones via C-C Bond Activation under Mild Conditions

The intermolecular deacylative coupling of unstrained ynones via C-C bond activation was accomplished by a CuCl-bpy system under mild reaction conditions. This protocol features facile cleavage of the C-C bond at room temperature, broad substrate scope, and efficient construction of important symmetric and unsymmetrical 1,3-diyne adducts through homo or cross coupling of ynones, respectively. The preliminary mechanistic investigations indicated that an acyl copper(III) complex is likely involved in this process.

Cooperative effect of spacer and Lewis base on highly reversible spectral changes of the octaethylporphyrin chromatic system in sensitivity, stability, and visibility to trifluoroacetic acid

The diacetylene-group connected chromatic system of [octaethylporphyrin]-[spacer]-[Lewis base] triads (OEP-SPC-LB) was conclusively studied, in which a trigger-like interaction of the terminal LB with trifluoroacetic acid (TFA) dramatically affects the inherent electronic properties of OEP. The 1HNMR, IR, and electronic absorption spectral properties of these OEP derivatives were examined, and were contemplated in view of a cooperative effect of SPC and LB on their OEP nucleus. Based on the results from this study, the structural elements for molecular design will be proposed in order to improve their reversible spectral changes between neutral and acidic media in terms of sensitivity, stability, and visibility to TFA.
