Assessment of the relative rates of the Diels-Alder reactions of the unsymmetrical diene 2-(trimethylsilyloxy)-1,3-cyclohexadiene (1) and its 6,6- and 5,5-dimethyl analogs 2 and 3 indicated that with symmetrical, ethylenic dienophiles (para-benzoquinone, maleic anhydride and N-phenylmaleimide) the Diels-Alder reaction is almost synchronous, but with tetracyanoethylene and with diethyl acetylenedicarboxylate the addition is sufficiently asynchronous as to lead to different rates of reaction with dimethyl-dienes 2 and 3.

New synthesis of Eucarvone 7, (+/-)-Nuciferal 12 and (+/-)-Manicone 16 are described from trimethylsilyl enol ethers 2, 10 and 14 via their chloromethylenation products by means of a two carbons homologation reaction.
