网页2016年6月14日 · Abstract. Recently, there has been an increasing use of the cyclopropyl ring in drug development to transition drug candidates from the preclinical to clinical stage. Important features of the cyclopropane ring are, the (1) coplanarity of the three carbon atoms, (2) relatively shorter (1.51 Å) C–C bonds, (3) enhanced π-character of C–C ...

Cyclopropyl Group - an overview | ScienceDirect Topics
网页A cyclopropyl group is a chemical group known for its biological activity and is found in many naturally occurring compounds. It can be incorporated into compounds through reactions like Diels Alder reactions with certain types of styrene.
Cyclopropanes - Wikipedia
网页Cyclopropanes are a family of organic compounds containing the cyclopropyl group. The parent is cyclopropane (C3H6). Synthesis and reactions. Most cyclopropanes are not prepared from the parent cyclopropane, which is somewhat inert. Cyclopropyl groups are often prepared by cyclization of 1,3-difunctional alkanes.
Cyclopropanation Strategies in Recent Total Syntheses
