Abstract: Abstract Asymmetric construction of β,β-diaryl substituted glycine bearing two contiguous chiral centers remains a significant challenge. Herein, the application of the para-quinone methides (p-QMs) and Ni(II)- complex of glycine via 1,6-conjugate addition to achieve asymmetric… read more here.

Abstract: Because of the high reactivity, N-carboxyanhydride (NCA) can be initiated by the thiol group. On the contrary, N-thiocarboxyanhydride (NTA) is more stable and is able to tolerate it. Herein, we apply cysteamine as a regioselective… read more here.
