Novel ambiphilic dichlorocarbenoid equivalent in alkene cyclopropanation and carbonyl olefination

The Ti-Mg-dichloromethylene complexes derived from the oxidative addition of CCl4 to the Mg-TiCl4 bimetallic species serve as a novel class of ambiphilic dichlorocarbenoid equivalents. Not only is Ti-Mg-dichlorocarbenoid highly selective but also it seems highly reactive in both alkene cyclopropanations and carbonyl dichloromethylenations.

Attempted Synthesis of Some α-Halolactones Fused in Bicycloheptanes

For the synthesis of the lactones A, B and C, compounds 4a, 4b, 10a and 10b were synthesized by dihalocyclopropanation and epoxidation of the dienes 1 and 7. 4a and 10a on hydrolysis give the corresponding diols 11 and 12.Treatment of 10a and 10b with BuLi/CO2 at -90 deg C gives the α-halocarboxylic acids 13a and 13b respectively.Both 13a and 13b on hydrolysis with 2N H2SO4 in acetone afford polymeric material, from which no pure product could be isolated.A dihydroxy-α-chlorocyclopropyl ester (17) has been synthesized from 1 but no lactone could be isolated.
