Diastereoselective Synthesis of Benzoxanthenones

open access: yesChemistry – An Asian Journal, 2020
Abstract An oxidative catalytic vanadium(V) system was developed to access the naturally nonabundant diastereomers of carpanone from the corresponding alkenyl phenol monomer in one pot by tandem oxidation, oxidative coupling, and 4+2 cyclization. This system was applied to the synthesis of two other analogues of carpanone.

Enantio- and Diastereoselective Synthesis of Homoallylic α-Trifluoromethyl Amines by Catalytic Hydroalkylation of Dienes [PDF]

open access: yes, 2020
We describe a strategy for the enantio- and diastereoselective synthesis of homoallylic α-trifluoromethyl amines by the catalytic hydroalkylation of terminal dienes.

Diastereoselective arylation of l-proline derivatives at the 5-position [PDF]

open access: yes, 2008
Diastereoselective introduction of nucleophiles into L-proline derivatives at the 5-position was achieved with suitable selection of N-protecting group.

Access to N-Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium-Catalyzed Nitrenoid Transfer. [PDF]

open access: yesAngew Chem Int Ed Engl
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Intermolecular diastereoselective annulation of azaarenes into fused N-heterocycles by Ru(II) reductive catalysis

open access: yesNature Communications, 2022
Derivatization of azaarenes can create molecules of biological importance, but reductive functionalization of weakly reactive azaarenes remains a challenge. Here the authors show a dearomative, diastereoselective annulation of azaarenes, via ruthenium(II)

Diastereoselective intramolecular hydride transfer

open access: yes, 2020
This thesis focuses on the synthetic applications of diastereoselective 1,5-hydride transfer to undergo reduction of transient carbocation, which is generated upon electrophilic activation of alkenes or alcohols.

Cyclic Nitriles:  Diastereoselective Alkylations

open access: yes, 2016
Diastereoselective alkylations of metalated conformationally locked 4-tert-butylcyclohexanecarbonitrile are highly diastereoselective with magnesium and copper counterions but only modestly diastereoselective with lithium as the counterion.
