    Ylides at a crossing: An unprecedented 1,3‐dipolar cycloaddition (cross‐cycloaddition) between two different ylides (see scheme) was realized by using the chiral CuI/tBu‐Phosferrox complex as the catalyst under mild reaction conditions. This catalytic system provides an expeditious approach to the construction of highly functionalized 1,2,4‐triazinane derivatives in good yields with excellent diastereoselectivities and enantioselectivities.
