TL;DR: In this paper, the reductive amination of cyclohexanone with ammonia over Cu-Cr-La/γ-Al2O3 was investigated and it was found that a proper solvent with high solubility of ammonia and 4A molecular sieves for the elimination of generated water contributed to cyclohexylamine formation in the premixing process.

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: A concise total synthesis of ieodomycin A and B was achieved in six and seven steps respectively from commercially available geraniol, which involved the construction of the C-5 hydroxyl via an Ti(OiPr)4/(S)-BINOL-mediated asymmetric aldol reaction as the key step as mentioned in this paper.

TL;DR: In this paper, a method for asymmetric synthesis of chain nonsaturated ester IeodomycinA and B was proposed, which utilizes geraniol as a raw material and utilizes Swern oxidation, 3-chloroperbenzoic acid epoxidation reaction, Wittig reaction and periodic acid oxidation cutting-off reaction.
