Structurally diverse 1,3-dienes are valuable building blocks in organic synthesis. Herein we report the iron-catalyzed coupling between α-allenyl esters and Grignard reagents, which provides a fast and practical approach to a variety of complex subs

A stereoselective domino inverse electron-demand Diels-Alder/amine group transfer reaction catalyzed by a bidentate Lewis acid provides 1-amino-1,2-dihydronaphthalenes, a core structure in many bioactive compounds. A concerted mechanism is proposed b

Presented herein is a mild, facile, and efficient iron‐catalyzed synthesis of substituted allenes from propargyl carboxylates and Grignard reagents. Only 1–5 mol % of the inexpensive and environmentally benign [Fe(acac)3] at −20 °C was suffici

Recently, we described the first inverse electron demand Diels–Alder reaction of 1,2-diazene catalyzed by a bidentate Lewis acid. Herein we investigate 1,2-phenylenediboronic esters as potential catalysts for this transformation offering higher sta

A domino inverse electron-demand Diels-Alder (IEDDA)/cyclopropanation reaction of diazines was discovered by applying electron-rich furans in the bidentate Lewis acid catalyzed IEDDA reaction. This process produces benzonorcaradienes in excellent yie

The inverse-electron-demand Diels–Alder (IEDDA) reaction catalyzed by a bidentate Lewis acid was applied to enamines generated in situ from aldehydes. In general, a high functional group tolerance has been observed. Side reactions during the enamin

A new concept for the catalysis of the inverse-electron-demand Diels-Alder (IEDDA) reaction of 1,2-diazenes using bidentate Lewis acid was recently reported by our group. The general catalytic principle is based on the simultaneous coordination of th

Bidentate Lewis acids were applied as catalysts for the inverse-electron-demand Diels–Alder (IEDDA) reaction of 1,2-diazines. The concept of catalysis is based on the coordination of the bidentate Lewis acid to both nitrogen atoms of the 1,2-diazin

A convenient iron-catalyzed method for the preparation of 1,2-bis(trimethylsilyl)benzenes is presented. Compared to the current procedures, low temperatures and toxic solvents are avoided, allowing large-scale preparation. Additionally, a variety of
