Rises in forests of binary shrubs

Discrete Mathematics & Theoretical Computer Science, 2017
The study of patterns in permutations associated with forests of binary shrubs was initiated by D. Bevan et al.. In this paper, we study five different types of rise statistics that can be associated with such permutations and find the generating functions for the distribution of such rise statistics.

Gram‐Scale Access to (3,11)‐Cyclotaxanes—Synthesis of 1‐Hydroxytaxuspine C

Angewandte Chemie International Edition, EarlyView.
Belonging to the family of complex taxanes, 1‐hydroxytaxuspine C is a densely functionalized natural product. The synthesis was realized via a semisynthetic approach, starting from commercially available 10‐deacetylbaccatin III. A late‐stage photocyclization was utilized to install the characteristic transannular bond of complex taxanes, transforming ...
