Abstract

A highly chemoselective three-component cascade reaction among alcohols or thiols, electron-deficient alkenes, and α,β-unsaturated ketones takes place under the catalysis of triethylamine, providing densely functionalized chain products in 44–99% yields. The transformation presumably proceeds through a sequential cascade of hetero-Michael/Michael reactions.

      DBU is generally regarded as a hindered and non-nucleophilic base, although there are a few reports contesting this viewpoint:

  • 10 Only the coupling products 4 were formed when the reactions were run, even in methanol (2.0 mL) under otherwise the same conditions.

  • 13 A control experiment also provided supportive evidence: In the absence of enone 2a and under the catalysis of Et3N (20 mol%), the hetero-Michael addition product of activated alkene 1a with methanol or ethanethiol was not observed at r.t. for 24 h.
