A one-pot, two-component InCl3-mediated cascade reaction has been developed. Starting from readily available β-keto ester and alkynal substrates, this cascade reaction provided highly functionalized 1-oxadecalins in good yields and excellent diastereoselectivities.

asymmetric Prins/Conia-ene cascade cyclization has been developed with In(OTf)3 in CH3CN from 0 to 70 °C. These conditions afforded very good yields of the 1-oxadecalin product in one pot and effectively suppressed the racemization of the 1-oxadecalin product with almost no enantiomeric excess (ee) loss. This cascade cyclization has been successfully employed for the construction of the highly functionalized
