A new palladiumâindium diastereoselective cascade allylation of imines using allenes and aryl iodides is described; N-tosyl and N-aryl homoallyl amines were obtained in moderate to good yields and excellent diastereoselectivity was observed when enantiomerically pure N-tert-butanesulfinyl imines were employed in the cascade.

Herein, a gold-catalyzedcascade reaction of yne-enones with iminooxindoles has been developed through a cascade cycloisomerization/(3 + 2) annulation process. This approach provides a straightforward and efficient route for the synthesis of functionalized 3,2′-pyrrolidinyl-spirooxindoles in high reactivity and broad substrate scope with excellent cis-selectivity. Moreover, the subsequent functionalization
