✦ Synopsis
Carbocyclic cis-(1.1.1)-Tris-σ-homobenzenes -Syntheses by Triple Epoxide → Cyclopropane Conversions, Structural Data, (. sigma.2s + σ2s + σ2s) Cycloreversions.
-A weakly basic mixed cyanocuprate carbon nucleophile is the reagent of choice to open the triple epoxide (I) to fully substituted cyclohexane derivatives such as (II), which in several group manipulations can be transformed into cyclopropane derivatives such as (III).
