Abstract
The reaction of cyclopentadiene with 1,1,3,3-tetrakis(methoxycarbonyl)propene gives an endo and exo mixture of dimethyl 2-{3,3-bis(methoxycarbonyl)bicyclo-[2.2.1]hept-5-en-2-yl}malonate, which by base-mediated retro-Michael reaction gives stereoselectively the cis-isomer of dimethyl 2-{4-[2,2-bis(methoxycarbonyl)vinyl]cyclopent-2-en-1-yl}malonate.
