Bioresource Technology, 2022
Hydrothermal liquefaction (HTL) of high-moisture biomass or biowaste to produce bio-oil is a promising technology. However, nitrogen-heterocycles (N-H) presence in bio-oil is a bottleneck to the upgrading and utilization of bio-oil.

N-Atom Deletion in Nitrogen Heterocycles.
Angewandte Chemie, 2021Excising the nitrogen in secondary amines, and coupling the two residual fragments is a skeletal editing strategy that can be used to construct molecules with new skeletons, but which has been largely unexplored.

Organic Letters, 2021
A method for regioselective ring openings of 3,4- and 2,3-epoxy alcohols with ambident nitrogen heterocycles is described. Using a diarylborinic acid catalyst, a single regioisomer is favored in couplings of nucleophile and electrophile partners that ...
