acid) (PS) microspheres to form core–shell structures, followed by removal of the PS core by etching in organic solvents. The as‐prepared hollow and multihollow microspheres were able to achieve better mass transfer in a complex heterogeneous asymmetric three‐component/triple cascade reaction and provided the products in good yields (31–61 %) with excellent stereoselectivities (80:20–93:7 dr, >99 % ee)

An asymmetric triple cascadeorganocatalyticreaction was carried out in water, which led to the construction of polyfunctional cyclohexene building blocks with multiple stereocenters with good diastereoselectivity and excellent enantioselectivity. This asymmetric triple cascade process was found to be quite effective for various nitroalkenes, including those with aliphatic substituents.
