We describe methods for synthesis of a triad molecular system based on mesoporphyrin II with electron-donor and electron-acceptor moieties for modeling the primary stage of charge separation in photosynthesis, differing in the order of addition of the donor and the acceptor.Using fluorescent spectroscopy, we have demonstrated quenching-containing coppounds.Investigation of the triad and its zinc complex by kinetic fluorescent spectroscopy allowed us to determine the electron transfer rate constants for the triad and for its zinc complex.

Herein we describe a one-pot microwave-assisted method for the synthesis of cinnamic acid and coumarin derivatives. The synthesis begins with an aldehyde synthon, and the chosen reaction conditions determine whether a cinnamic acid or coumarin derivative is formed. A regioselective Claisen rearrangement was also efficiently incorporated into the synthetic sequence to further increase the complexity of the product. Notably, this approach provides high product yields and selectivities without the need of a phenol protecting group.

This study describes the first para-selective palladium-catalyzed alkenylation of tertiary amines. This regioselective C-H activation was conducted without any chelation moieties. A series of olefins were reacted under mild reaction conditions at 60 °C, and the corresponding products were obtained in good yields with high selectivity.
