TL;DR: This work presents an approach to synthesize n-type flexible thermoelectric materials through a facile electrochemical intercalation method, fabricating a hybrid superlattice of alternating inorganic TiS2 monolayers and organic cations.
Journal ArticleDOI
Enantioselective formal α-allylation of nitroalkanes through a chiral iminophosphorane-catalyzed Michael reaction–Julia–Kocienski olefination sequence
TL;DR: This new methodology relies on the development of a highly diastereo- and enantioselective conjugate addition of nitroalkanes to vinylic 2-phenyl-1H-tetrazol-5-ylsulfones using chiral triaminoiminophosphorane as a requisite base catalyst and subsequent Julia-Kocienski olefination under kinetic conditions.
Journal ArticleDOI
Molecular Design, Synthesis, and Asymmetric Catalysis of a Hexacoordinated Chiral Phosphate Ion
TL;DR: It is demonstrated that the corresponding hydrogen phosphate acts as an effective catalyst for a highly enantioselective Pictet-Spengler-type reaction, wherein the relationship between the structure of the chiral phosphate ion and its ability to dictate the absolute stereochemistry is revealed in conjunction with precise structural elucidation of the phosphate ion.
Journal ArticleDOI
Allenedicarboxylate as a Stereochemically Labile Electrophile for Chiral Organic Base-catalyzed Stereoselective Michael Addition
TL;DR: In this paper, a highly stereoselective Michael addition of α-amino acid-derived 2-benzyloxythiazol-5(4H)-ones to dimethyl allenedicarboxylate was developed by employing P-spiro chiral triaminoiminophosphorane bearing (S)-sec-butyl groups as a catalyst.
Journal ArticleDOI
Enantioselective Formal α‐Allylation of Nitroalkanes Through a Chiral Iminophosphorane‐Catalyzed Michael Reaction—Julia—Kocienski Olefination Sequence.
TL;DR: P-chiral phosphoranes are employed as catalyst in the highly anti-diastereoselective and enanti-selective Michael reaction of vinyl sulfonates with nitroalkenes under kinetic conditions as mentioned in this paper.
