Chiral condensed matter systems, such as liquid crystals and magnets, exhibit a host of spatially localized topological structures that emerge from the medium's tendency to twist and its competition with confinement and field coupling effects. We show that the strength

Starting with Gauss and Kelvin, knots in fields were postulated to behave like particles, but experimentally they were found only as transient features or required complex boundary conditions to exist and could not self-assemble into three-dimensional crystals. We introduce energetically

商品

由Seebach小组开发的手性助剂TADDOL(α,α,α,α-四芳基-1,3-二氧戊环-4,5-二甲醇)在不对称合成中具有多种应用,包括从用作化学计量手性试剂或用于路易斯酸介导的反应,到在催化加氢和立体规则复分解聚合中发挥作用。

TADDOL chiral auxiliaries find diverse applications in asymmetric synthesis, catalysis, and polymerization.

TADDOLs demonstrate versatility in metal-catalyzed asymmetric reactions and as Brønsted acid organocatalysts in hetero-Diels–Alder reactions.
