A Major Facilitator Superfamily Transporter Contributes to Ergot Alkaloid Accumulation but Not Secretion in Aspergillus leporis

Applied Microbiology
Ergot alkaloids are fungal natural products with important roles in agriculture and medicine. We used heterologous expression and gene knockout approaches to investigate potential roles for the product of a major facilitator superfamily transporter gene (

Regioselective Formation of Substituted Indoles: Formal Synthesis of Lysergic Acid.

Chemistry, 2020
A Diels-Alder reaction-based strategy for the synthesis of indoles and related heterocycles is reported. An intramolecular cycloaddition of alkyne-tethered 3-aminopyrones gives 4-substituted indolines in good yield and with complete regioselectivity ...
