Phenanthrenes/dihydrophenanthrenes: The selectivity controlled by different benzynes and allenes

A method for the intermolecular annulation of benzynes with allenes is disclosed. This protocol utilized allenes as an unconventional diene component for the selective synthesis of phenanthrenes and dihydrophenanthrenes under the control of different benzyne precursors, featuring high atom-economy and good functional group compatibility. Density functional theory (DFT) calculations reveal that different migratory routes of the aromatic C-H bond are crucial for the observed selectivity. This journal is

Fully Substituted Conjugate Benzofuran Core: Multiyne Cascade Coupling and Oxidation of Cyclopropenone

An unprecedented C═C double bond cleavage of cyclopropenone and dioxygen activation by multiyne cascade coupling has been developed. This chemistry provides a novel, simple, and efficient approach to synthesize fully substituted conjugate benzofuran derivatives from simple substrates under mild conditions. The density functional theory (DFT) calculations reveal that the unique homolytic cleavages of cyclopropenone and molecular oxygen are crucial to the success of this reaction.

2-aldehyde indole compound and preparation method thereof

The invention provides a 2-aldehyde indole compound and a preparation method thereof. The 2-aldehyde indole compound is obtained by taking a tetraacetylene compound and 2-phenyl-2-oxazoline as raw materials and reacting in a toluene solvent. Compared with the prior art, the invention provides a brand-new synthesis method of 2-formyl indole, and a new 2-formyl indole compound is generated. The synthesized 2-aldehyde indole compound has relatively high atom economy, is more complex and diverse in structure, and has a certain application prospect.
