Highly Enantioselective Organocatalyzed Construction of Quaternary Carbon Centers via Cross-Aldol Reaction of Ketones in Water
TL;DR: In this article, the asymmetric construction of quaterna- ry carbon centers via cross-aldol reactions of ke- tones with b,g-unsaturated keto esters catalyzed by 4-(tert-butyldiphenylsilyloxy)-pyrrolidine-2-carbox- ylic acid in water is described.

Spiro-configured phenyl acridine thioxanthene dioxide as a host for efficient PhOLEDs
Maxime Romain,Denis Tondelier,Bernard Geffroy,Anna Shirinskaya,Olivier Jeannin,Joëlle Rault-Berthelot,Cyril Poriel +6 more
TL;DR: A new high triplet organic semi-conductor based on a donor-spiro-acceptor design has been synthesised and used as a host material in high performance (EQE = 11.4%) sky blue phosphorescent organic light emitting diodes.
Journal ArticleDOI
Regioselective synthesis of tetrahydrothiochromen-5-ones via a one-pot three-component solvent-free domino protocol.
TL;DR: A highly efficient one-pot three-component regioselective synthesis of 4-aryl-3-aroyl-2-methylsulfanyl-4,6,7,8-tetrahydrothiochromen-5-ones has been developed by annulation of β-oxodithioesters with aldehydes and cyclic 1,3-diketones under solvent-free conditions promoted by P(2)O(5).

Highly Stereoselective and Scalable anti-Aldol Reactions using N-(p-dodecylphenylsulfonyl)-2-Pyrrolidinecarboxamide: Scope and Origins of Stereoselectivities
TL;DR: Density functional theory computations reveal that the origins of enhanced diastereoselectivity are due to the presence of nonclassical hydrogen bonds between the sulfonamide, the electrophile, and the catalyst enamine that favor the major anti-Re aldol TS in the Houk-List model.
Journal ArticleDOI
Tandem Prins/Friedel–Crafts cyclization for stereoselective synthesis of heterotricyclic systems.
TL;DR: Though the Prins cyclization proceeds smoothly under the influence of Sc(OTf)(3), high conversions and enhanced reaction rates are achieved using a mixture of Sc (OTf) and TsOH (1:3).
