Improved power efficiency in blue phosphorescent organic light-emitting diodes (PHOLEDs) was demonstrated by using new high triplet energy hole-transport materials based on the diphenylmethyl linkage. Two high triplet energy hole-transport materials with diphenylamine or ditolyamine moieties linked through a diphenylmethyl linkage, 4,4?-(diphenylmethylene)bis(N,N- diphenylaniline) (TCBPA) and 4,4?-(diphenylmethylene)bis(N,N-di-p- tolylaniline), were synthesized and evaluated as hole-transport materials for blue PHOLEDs. The power efficiency of TCBPA was superior to that of standard 1,1-bis[4-[N,N?-di(p-tolyl)amino]phenyl]cyclohexane.

We report the palladium-catalyzed asymmetric allylic alkylation of 1,4-diazepan-5-ones. This reaction proceeds smoothly to give gem-disubstituted diazepanone heterocycles bearing various functional groups in up to >99% yield and up to 95% ee. An electron-rich p-anisoyl lactam protecting group and the use of a nonpolar solvent proved crucial to obtaining high enantioselectivity in most cases. Additionally, we demonstrate the use of our methodology in the synthesis of a gem-disubstituted analogue of the FDA-approved anti-insomnia drug suvorexant.

Sulfur-heterocycles are found in nature and they are recognized by biological systems as effective pharmacophores inducing anticancer, antimicrobial, antiviral, anti-diabetic activities via e.g. blocking functionality of many enzymes and receptors. Due to the biological importance of sulfur heterocycles, novel and efficient synthetic strategies, opening the access to regio- and stereoselective construction and functionalization of these scaffolds are in high demand. The advantages and some limitations of tandem strategies are discussed in view of challenges related to the construction of adequately functionalized or fused main heterocyclic sulfur frameworks of biological interest. In addition, examples of sulfur-heterocycles of important biological potency as well as domino reaction mechanisms revealing novel possibilities and ideas for construction of these attractive molecules, are reviewed. Bibliography presented in this review contains references to papers, which appeared mainly during the period from 2009 to 2018.

New drugs introduced to the market every year represent privileged structures for particular biological targets. These new chemical entities (NCEs) provide insight into molecular recognition and also serve as leads for designing future new drugs. This annual review covers the synthesis of thirty-seven NCEs that were approved for the first time in 2014 and one drug which was approved in 2013 and was not covered in a previous edition of this review.

A facile synthesis of gamma,delta-unsaturated ketones via palladium-catalyzed ring-opening of 2-alkylidenecyclobutanols with organic halides is described. The key step involves Csp3 ? Csp2 bond cleavage via palladium-catalyzed beta-carbon elimination. The desired gamma,delta-unsaturated ketones are obtained in good to excellent yields and broad functional group tolerability. Aryl, heteroaryl, benzyl, and alkynyl halides all readily participate to forge tri-substituted carbon-carbon double bond in a stereoselective manner. (Figure presented.).

Current methods for functional group interconversion have, for the most part, relied on relatively strong driving forces which often require highly reactive reagents to generate irreversibly a desired product in high yield and selectivity. These approaches generally prevent the use of the same catalytic strategy to perform the reverse reaction. Here we describe a catalytic functional group metathesis approach to interconvert, under CO-free conditions, two synthetically important classes of electrophiles that are often employed in the preparation of pharmaceuticals and agrochemicals?aroyl chlorides (ArCOCl) and aryl iodides (ArI). Our reaction design relies on the implementation of a key reversible ligand C?P bond cleavage event, which enables a non-innocent, metathesis-active phosphine ligand to mediate a rapid aryl group transfer between the two different electrophiles. Beyond enabling a practical and safer approach to the interconversion of ArCOCl and ArI, this type of ligand non-innocence provides a blueprint for the development of a broad range of functional group metathesis reactions employing synthetically relevant aryl electrophiles.
