Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Synthesis of proline analogs via Rh-catalyzed asymmetric conjugate addition.Product Details of 36620-11-8.
An enantio- and diastereoselective Rh-catalyzed conjugate addition reaction for the synthesis of proline analogs is reported. A high-throughput experimentation campaign was used to identify an efficient chiral catalyst which was able to afford the desired products in high yield and with high levels of diastereo- and enantioselectivity. This method was used to afford a range of 3-substituted proline derivatives from readily available dehydroproline electrophiles and boronic acid nucleophiles.
