Visible light mediated azomethine ylide formation—photoredox catalyzed [3+2] cycloadditions

Arynes are among the most active organic intermediates and have found numerous applications in expeditious preparation of substituted arenes. In the past 20 years, chemists have witnessed a resurgence in aryne chemistry, which is mainly attributed by the extensive utilization of Kobayashi's method, a fluoride-induced removal of the TMS group with concomitant departure of its ortho OTf group on o-silylaryl triflates. Nowadays, o-silylaryl triflates are the most frequently employed aryne precursors. This review provides an overview of the history of Kobayashi's method, its methodological achievements, and its applications in the synthesis of natural products, bioactive molecules, and polycyclic aromatic hydrocarbons.

Synthesis of Benzoazocines from Substituted Tetrahydroisoquinolines and Activated Alkynes in a Tetrahydropyridine Ring Expansion

The construction of N-heterocyclic rings represents a very important and fast-developing area of organic synthesis. In this context, electrochemistry has emerged as a mild solution for generating in situ the required electrophilic substrates, bases and nucleophiles derived from low-level and extremely stable reagents, the further application of which makes some heterocycles more accessible. In this review, we have covered the recent advances in the electrochemical synthesis of five- and six-membered N-heterocyclic compounds published from 2017 to October 2018. 1 	Introduction 2 	Electrochemical Synthesis of Five-Membered N-Containing Heterocycles 2.1 	Pyrrolidines 2.2 	Imidazoles 2.3 	Pyrazoles 2.4 	Triazoles 2.5 	Oxazoles 2.6 	Indoles 2.7 	Thiazoless 3 	Electrochemical Synthesis of Six-Membered N-Containing Heterocycles 3.1 	Piperidines and Pyridines 3.2 	Quinazolinones 3.3 	Benzoxazines 4 	Conclusions
