Light-induced valley polarization in interacting and nonlinear Weyl semimetals
It has been recently predicted that the interplay between Coulomb interactions and Berry curvature can produce interesting optical phenomena in topologically nontrivial two-dimensional insulators. Here, we present a theory ...
Short approach toward the nonracemic A,B,E tricyclic core of calyciphylline B-type alkaloids
Abstract: A suitably functionalized tricyclic adduct containing the common A,B,E rings found in calyciphylline B-type alkaloids was obtained in nine linear steps. The key transformation features an efficient one-pot sequence ...
General approach toward aspidospermatan-type alkaloids using one-pot Vilsmeier–Haack cyclization and azomethine ylide cycloaddition
Abstract: The development of a new one-pot reaction sequence afforded the tricyclic core of several aspidospermatan-type alkaloids from a linear, densely functionalized substrate. The key sequence features a highly ...
