Highly Syn-?-Facial Preference in the Diels-Alder Reactions of 1,2,3,4,5-Pentamethylcyclopentadienes Having Carboxy, Ethoxycarbonyl, and Cyano Substituents at 5-Positions

Diels-Alder reactions of 1,2,3,4,5-pentamethylcyclopentadienes having carboxy, alkoxyccarbonyl, and cyano substituents at 5-positions with N-phenylmaleimide preferentially afforded the corresponding syn-attack products with the ratio of syn/anti=80 : 20 to 100 : 0, while the diene having 5-hydroxymethyl moiety gave the anti-attack product exclusively.

On the Reaction of (Pentamethylcyclopentadienyl)lithium with Halomethanes and Formyl Compounds

In view to the synthesis of pentamethylcyclopentadienyl-substituted methane derivatives ("pentamethylcyclopentadienyl-carbon compounds") reactions of (pentamethylcyclopentadienyl)lithium with halomethans, formates, and corbon dioxide were investigated.While treatment with tri- and tetrahalomethanes leads to benzene derivatives via molecular rearrangement, reactions with formates and carbon dioxide yield pentamethylcyclopentadienyl-substituted methane derivatives.Attempts to prepare disubstituted species show the formation of by-products only.
