TL;DR: The resulting Ag@UCPP as a heterogeneous catalyst exhibited excellent activity for the carboxylative cyclization of propargyl alcohols with CO2 under mild conditions, together with good recyclability, probably attributed to the synergistic effect of the UCPP on the adsorption and activation of CO2 and the immobilization of Ag nanoparticles.

TL;DR: In this article, a concise total synthesis of (+)-brazilin from readily available 4-bromo-1,2-dimethoxybenzene was described, where a Sharpless asymmetric dihydroxylation was employed to introduce the chiral hydroxyl group and trifluoroacetic acid (TFA) catalyzed one-pot intramolecular tandem Prins/Friedel-Crafts reaction was also involved as the key transformation in the construction of the hybrid chromane and indane framework.

TL;DR: In this article, a unified asymmetric total synthesis of (+)-porantheridine and (−)-6-epi-PORANTHERidine has been achieved via a Horner-Wadsworth-Emmons/aza-Michael addition reaction or diastereoselective nucleophilic substitution of 2-methoxypiperidine from a common intermediate.

TL;DR: A concise formal synthesis of (±)-aplykurodinone-1 starting from a commercially available material and based on the indium-catalyzed Conia-ene reaction has been accomplished as mentioned in this paper.
