TL;DR
DBU-catalyzed reactions of salicylic aldehydes with 3-methylpenta-3,4-dien-2-one, 3-benzylpenta/3-4- dienoate gave the corresponding functionalized 2H-1-chromenes in good to excellent yields and good diastereoselectivities in some cases in DMSO, respectively.
Abstract
[reaction: see text] DBU-catalyzed reactions of salicylic aldehydes with 3-methylpenta-3,4-dien-2-one, 3-benzylpenta-3,4-dien-2-one, or ethyl 2-methylbuta-2,3-dienoate gave the corresponding functionalized 2H-1-chromenes in good to excellent yields and good diastereoselectivities in some cases in DMSO, respectively.

To the knowledge, this is the first discovery of anti-JH, and it is hoped it will guide the way to the emergence of a fourth generation of safe and insect-specific pesticides.

First experimental evidence is reported that thin islands of gold in fact have the same CO adsorption behavior as large gold particles and extended gold surfaces, and observed differences in reactivity of gold nanoparticles are proposed to arise from the presence of highly uncoordinated gold atoms.
