Genomics of ecological adaptation in Canary Island Descurainia (Brassicaceae) and comparisons with other Brassicaceae

Autor: Amy C. Jackson, Mark A. Carine, Mark A. Chapman

Publikováno v: Ecology and Evolution, Vol 14, Iss 8, Pp n/a-n/a (2024)

Abstract Oceanic archipelagos provide striking examples of lineages that have radiated over pronounced ecological gradients. Accompanying this diversification, lineages have evolved adaptations allowing survival in extreme environments. Here, we inve

The role of geography, ecology, and hybridization in the evolutionary history of Canary Island Descurainia

Autor: Amy C. Jackson, Oliver W. White, Mark Carine, Mark A. Chapman

Premise: oceanic islands offer the opportunity to understand evolutionary processes underlying rapid diversification. Along with geographic isolation and ecological shifts, a growing body of genomic evidence has suggested that hybridization can play

Total Syntheses of (±)-Dracocephalone A and (±)-Dracocequinones A and B

Autor: Taehwan Hwang, Joseph P. Tuccinardi, Alexandra A. Beard, Amy C. Jackson, Min J. Jung, John L. Wood

Publikováno v: Angewandte Chemie (International ed. in English). 61(46)

Described herein are the first total syntheses of (±)-dracocephalone A (1) and (±)-dracocequinones A (4) and B (5). The synthesis was initially envisioned as proceeding through an intramolecular isobenzofuran Diels-Alder reaction, a strategy that e

A Ring Expansion Approach To N-oxy-2,5-diketopiperazines

Autor: Amy C. Jackson, James T. Olsen, Sasha Sundstrom, Kyle M. Lambert, John L. Wood

Publikováno v: Tetrahedron Lett

A ring expansion of tetramic acids (pyrrolidine-2,4-diones) to N-oxy-2,5-diketopiperazines (DKPs) is described. This method allows for the facile and late-stage construction of the hydroxamic acid moiety and can thereby serve as a general method for

Total Synthesis of (±)‐Phyllantidine: Development and Mechanistic Evaluation of a Ring Expansion for Installation of Embedded Nitrogen‐Oxygen Bonds

Autor: Sam Yruegas, Joshua B. Cox, Kenneth B. Wiberg, John L. Wood, Lin Liu, Amy C. Jackson, Kyle M. Lambert

Publikováno v: Angew Chem Int Ed Engl

The development of a concise total synthesis of (±)-phyllantidine (1), a member of the securinega family of alkaloids containing an unusual oxazabicyclo[3.3.1]nonane core, is described. The synthesis employs a unique synthetic strategy featuring the

Toward a Catalytic Atroposelective Synthesis of Diaryl Ethers Through C(sp2)–H Alkylation with Nitroalkanes

Autor: Jeffrey L. Gustafson, Andrew N. Dinh, Sean T. Toenjes, Amy C. Jackson, Sean M. Maddox, Mirza A. Saputra, Ryan R. Noorbehesht

Publikováno v: Synlett. 29:2155-2160

We report studies toward a small-molecule-catalytic approach to access atropisomeric diaryl ethers that proceeds through a C(sp2)–H alkylation using nitroalkanes as the alkyl source. A quaternary ammonium salt derived from quinine, containing a ste
