Özet

A 2-step 100% atom economic sequence is reported whereby active methylene pronucleophiles react with 2 mol equiv. of allene to give bis-1,3-dienylmethyl derivatives of the pronucleophiles. Subsequent double Diels-Alder reactions furnish 1,1'-linked cyclohexenes with a 3-carbon spacer. (C) 2001 Published by Elsevier Science Ltd.
