Abstract:
The first rationalized crown ether-bis(porphyrin) conjugate with a large ring-based conformation flexibility 1 has been synthesized; the achiral-to-chiral transformation upon complexation with chiral diamines is assisted by K(+) accommodated in the crowned moiety, and it is possible to determine the chirality of carboxylates as potassium salts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Thermal Electrocyclic Reactions: Stereochemistry
Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
