Allenylphosphine oxides as simple scaffolds for phosphinoylindoles and phosphinoylisocoumarins
Beilstein Journal of Organic Chemistry, 2014 A range of phosphinoylindoles was prepared in one-pot from functionalized propargyl alcohols and a suitable P(III) precursor via a base-mediated reaction. The reaction proceeds via the intermediacy of allenylphosphine oxides.

Synthesis of 2-substituted tryptophans via a C3- to C2-alkyl migration
Beilstein Journal of Organic Chemistry, 2014 The reaction of 3-substituted indoles with dehydroalanine (Dha) derivatives under Lewis acid-mediated conditions has been investigated. The formation of 2-substituted tryptophans is proposed to occur through a selective alkylative dearomatization ...

A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles
Advanced Science, EarlyView.Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.

Advanced Science, EarlyView.AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...
