A new very mild K2CO3-catalysed one-pot two-carbon ring expansion of cyclopentanones

Abstract

Cyclic α-carbonyl-substituted cyclopentanones undergo, in a one-pot process, an unprecedented K2CO3-catalysed cascade Michael addition-regioselective aldol cyclisation-reverse Dieckmann reaction with α,β-unsaturated aldehydes in methanol or ethanol at room temperature to afford stereoselectively substituted cycloheptane derivatives.
