Intramolecular annulations of donor–acceptor cyclopropanes [PDF]

, 2010
The intramolecular reaction of donor–acceptor cyclopropanes with various dipoles and dipolar equivalents allows access to a variety of bicyclic adducts with good stereocontrol. The linkers can often be cleaved to provide stereodefined products.

Highly efficient construction of angular polycycles [PDF]

Nature Communications
Angular tricyclic and polycyclic skeletons feature typical cores in an intriguing type of natural products. We herein report the Lewis acids-catalyzed dearomative (3 + 2) cycloadditions of donor-acceptor cyclopropanes with benzene ring, by which ...

Triazene-Activated Donor–Acceptor Cyclopropanes: Ring-Opening and (3 + 2) Annulation Reactions

, 2020
Donor–acceptor cyclopropanes substituted with 3,3-dialkyltriazenyl groups are described herein. The strong electron-donating character of the triazene renders the cyclopropanes highly reactive, allowing for catalyst-free ring-opening reactions with ...
