摘要

Qr 1 0 at 25 OC in the presence of diphenylisobenzofuran (DIBF) afforded crystalline adduct 6 in 24% yield after chromatography. The structure of 6 (C, symmetry) was confidently assigned from spectral data and DDQ oxidation to 7.9 Ample literature precedent supports the conclusion that 6 is formed from [2+ 41 cycloaddition of cumulene 1 at its most strained A Synthesis of conjugated enyne 2 (Scheme 11) follows a similar strategy in the final step. ...
