Intramolecular Heck Reaction in Total Synthesis of Natural Products: An Update

This review article disclosed the recent uses of intramolecular Heck reaction in total synthesis of natural products. During this survey the role of different conditions for effective Heck cyclization has been discussed which will be useful to the chemistry community in broader aspects. Abstract This review highlights the application of intramolecular...

Ru(II)‐Catalyzed Regioselective Hydroarylative Coupling of Indolines with Internal Alkynes by C−H Activation

A hydroarylative coupling of internal alkynes with indolines and tetrahydroquinolines has been developed using the bench‐stable and inexpensive ruthenium (II) catalyst. The applicability of this methodology has been demonstrated by the late stage functionalization of natural products, biologically active molecules, and APIs. Abstract We have...

Recent Advances in Retained and Dehydrogenative Dual Functionalization Chemistry

Dual functionalizations in organic synthesis is an elegant and powerful method for simultaneously introducing two different functional groups regio‐selectively into a target molecule. This review describes recent advances in dual functionalization, focusing on the retained dual functionalization and dehydrogenative dual functionalization. Abstract...

Chemoselective Deoxygenation of 2° Benzylic Alcohols through a Sequence of Formylation and B(C6F5)3‐Catalyzed Reduction

A sequence of formylation and B(C6F5)3‐catalyzed reduction of the resulting formate with Et3SiH enables the chemoselective deoxygenation of secondary (2°) benzylic in the presence of primary (1°) benzylic and tertiary (3°) non‐benzylic alcohols. Both steps are chemoselective with the formylation favoring 1° and 2° over 3° and the reduction favoring...

A General Stereocontrolled Synthesis of Opines through Asymmetric Pd‐Catalyzed N‐Allylation of Amino Acid Esters

A palladium catalyst prepared in situ from a tartrate‐derived C2‐symmetric diphosphane enables the highly stereoselective N‐allylation of amino acid esters. The products are efficiently converted into natural and unnatural opines, which are of relevance due to their biological properties. Abstract A stereo‐divergent synthesis of natural and...

Cover Feature: Luminescent Ionic Liquid Crystals Based on Naphthalene‐Imidazolium Unit (Eur. J. Org. Chem. 14/2021)

The Cover Feature shows a luminescent ionic naphtalene molecular structure. By playing with the nature of the anion and the amphipathic character, it is possible to promote luminescence properties in the three states of matter (solid, liquid crystal, and liquid) as well as to control the supramolecular mesomorphic architecture in layers (black triangle...

Front Cover: Recent Advances in Retained and Dehydrogenative Dual Functionalization Chemistry (Eur. J. Org. Chem. 14/2021)

The Front Cover shows two sorcerers casting a spell of “retained dual functionalization”, which retains the binding mode of two reactive atoms in functionalization acceptors, and “dehydrogenative dual functionalization”, which involves the rehybridization of an sp3 orbital into an sp2 orbital by the installation of two functional groups, on the molecules...

Luminescent Ionic Liquid Crystals Based on Naphthalene‐Imidazolium Unit

The convergence of fields of ionic liquid crystal chemistry, those of imidazolium salts, luminescence and liquid crystals, could lead to a wide range of new materials with original supramolecular properties. An efficient three‐step synthetic method is developed in order to obtain luminescent naphthalene‐imidazolium‐anion compounds in the three states...

Strigolactones: Phytohormones with Promising Biomedical Applications

Strigolactones are a class of carotenoid derived plant hormones which impact many functions of plant metabolism in response to environmental stress. They also act as exogenous signals perceived by both mycorrhizal fungi and parasitic plants. The peculiar chemical skeleton of these molecules and their mode of action in plants inspired possible applications...

Lithium Hydroxide Assisted Endo‐Selective [4+4]‐Photocycloaddition of Pyran‐2‐ones

Readily accessible 3‐acyl‐4‐hydroxypyran‐2‐ones with pendent furans undergo [4+4]‐photocycloaddition reactions in the presence of lithium ion to afford lactone‐bridged cyclooctenones with complete selectivity for the endo cycloadducts. Abstract 3‐Acyl‐4‐hydroxypyan‐2‐ones with pendent furans, readily available from dehydroacetic acid, are substrates...
