摘要：

A number of novel tandem sequences initiated by a retro-aldol process are described along with preliminary scope and limitation studies. These include (i) retro-aldol/Wittig trapping/intramolecular Michael addition, (ii) retro-aldol/aza-Wittig/intramolecular imine addition, (iii) retro-aldol/Henry/intramolecular Michael addition and (iv) retro-aldol/Knoevenagel/intramolecular Michael addition sequences. A range of novel functionalised cyclopentanes, and related systems, are described which should prove to be useful synthetic building blocks. (C) 2009 Elsevier Ltd. All Fights reserved.
