Abstract: | The stereochemistry of the adducts formed from the cycloaddition of tetracyclone, phencyclone and 2-methyl-3,4,5-triphenylcyclopenta-2,4-dienone with cis-3,4-dichlorocyclobutene (in one case with 3-chloro-4-methoxycyclobutene) has been evaluated in a rigorous fashion. This allows a firmly-based caveat to be issued regarding the p.m.r. probe for stereochemical evaluation of tetracyclone adducts recently proposed by Coxon and Battiste. |
