  10-montmorillonites, activated by several methods, are used as catalysts in the reaction between methyl acrylate and cyclopentadiene. Calcined clays are better catalysts than dried clays. Zn(II) clays, dried and calcined, are compared as catalysts of the asymmetric Diels-Alder reaction between (−)-methyl acrylate and cyclopentadiene. Calcined clay again shows a higher catalytic activity and leads to better

  Silica and alumina, modified by treatment with AlClEt2 and TiCl4, are tested as catalysts in the reactions of cyclopentadiene (1) with (-)-menthyl acrylate (2a), (R)-O-acryloyl pantolactone (2b) and (S)-O-acryloyl lactate (2c). Silica-modified systems are the most efficient heterogeneous catalysts described to date for this kind of reaction, leading to selectivities similar to those obtained with aluminium homogeneous catalysts. Whereas silica. AlClEt2 is better for the reaction of 2a and 2c, silica. TiCl4 is more suitable for the reaction of 2b.
