Fascinating Natural and Artificial Cyclopropane Architectures

Abstract

It is amazing what three carbons can do! Nature, industry, and chemists working in academia continue to explore the cyclopropane moiety from various perspectives, among them biological activity, reactivity, and synthetic methodology. Breathtaking multiple cyclopropane ring structures such as 1 and 2 have recently been prepared and represent milestones in the field of small-ring chemistry.
