Metal- and Acid-Free C-H Formylation of Nitrogen Heterocycles: Using Trioxane as an Aldehyde Equivalent Enabled by an Organic-Soluble Oxidant.

Organic Letters, 2018
A metal-free, innate, and practical C-H formylation of nitrogen heterocycles using trioxane as a formyl equivalent is reported. This reaction provides a mild and robust method for modifying medicinally relevant heterocycles with an aldehyde handle.

Synthesis of nitrogen heterocycles

2017
Part I: The first part of this thesis describes efforts towards the Lycopodium alkaloids lycopladine H and lycojaponicumin D and the chemistry developed in the course of these studies. We first pursued a divergent transannular Mannich reaction from a medium-size ring precursor.
