Abstract
A combination of Yb(OTf)3 and TMSCl influenced the outcome of cross-aldol reactions of cycloalkanones and benzaldehyde. Interestingly, reaction of cycloheptanone and cyclooctanone with aldehydes under the Yb(OTf)3–TMSCl reagent system provides 3-(2-oxocycloalkyl)-3-phenylpropanals in conjunction with the corresponding aldol products.Keywords
