Tetrazoles have been widely studied for their biological properties. An efficient route for large-scale synthesis of 1,5-disubstituted tetrazoles (1,5-DTs) is presented. The strategy exploits a reductive approach to synthetize a cyclic chiral imine substrate which is then converted into the target product through an Ugi-azide three-component reaction (UA-3CR). The final products are equipped with additional functionalities which can be further elaborated for the generation of combinatorial libraries of enantiopure heterocycles.
A cascade strategy enables a total synthesis of (-)-gephyrotoxin

A concise and efficient synthesis of (-)-gephyro-toxinfrom L-pyroglutaminol has been realized. The key step in this approach is a diastereoselective intramolecular enamine/ Michael cascade reaction that forms two rings and two stereocenters and generates a stable tricyclic iminium cation. A hydroxy-directed reduction of this intermediate plays a key role in establishing the required cis-decahydroquinoline ring system, enabling the total synthesis of (-)-gephyrotoxin in nine steps and 14 % overall yield. The absolute configuration of the synthetic material was confirmed by single-crystal X-ray diffraction and is consistent with the structure originally proposed for material isolated from the natural source.

supporting information, p. 2863 - 2867 (2021/05/05)
The Pt-catalyzed diboration of cyclic alkenes is extended to unsaturated heterocycles and bicyclic compounds and can be accomplished in a diastereoselective fashion. The optimal procedures, substrate scope, and diastereoselectivity were investigated, and examples employing both homogeneous and heterogeneous catalysis were examined. Lastly, application to the construction of the nucleoside analog (±)-aristeromycin was conducted.
