Diastereoselective synthesis of non‐proteinogenic α‐amino acids
, 2008 International audienceThe synthesis of enantiomerically pure azatyrosine, tribromophenylalanine and trichlorophenylalanine is described, using two methods, diastereoselective alkylation and (or) diastereoselective protonation of chiral ...

FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway
Chemistry – A European Journal, EarlyView.Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

The synthesis of the 2,3-difluorobutan-1,4-diol diastereomers
Beilstein Journal of Organic Chemistry, 2017 The diastereoselective synthesis of fluorinated building blocks that contain chiral fluorine substituents is of interest. Here we describe optimisation efforts in the synthesis of anti-2,3-difluorobutane-1,4-diol, as well as the synthesis of the ...

Chemistry – A European Journal, EarlyView.Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

A concise enantioselective synthesis of the guaiane sesquiterpene (−)-oxyphyllol
Beilstein Journal of Organic Chemistry, 2013 (−)-Oxyphyllol was prepared in only 4 steps from an epoxy enone that already served as an intermediate for the total synthesis of the anticancer guaiane (−)-englerin A.
