Synthesis of Vinylcyclopropanes by Intramolecular Epoxide Ring Opening. Application for an Enantioselective Synthesis of Dictyopterene A
The reaction of functionalized oxiranes 1 with the sulfur- or silicon-stabilized anions 2 provides β-heteroatom-substituted γ,δ-unsaturated epoxides 5 with, for 5e,f, a trans C=C moiety.A cis compound 9 is obtained using acetylide anion 2c via 7 and subse
