Abstract
Pd-catalyzed enantioselective alkylation in conjunction with further synthetic elaboration enables the formal total syntheses of a number of "classic" natural product target molecules. This publication highlights recent methods for setting quaternary and tetrasubstituted tertiary carbon stereocenters to address the synthetic hurdles encountered over many decades across multiple compound classes spanning carbohydrate derivatives, terpenes, and alkaloids. These enantioselective methods will impact both academic and industrial settings, where the synthesis of stereogenic quaternary carbons is a continuing challenge.

Abstract
We previously achieved NHC-mediated preparation of ester-type fluoroalkene dipeptide isosteres (ES-FADIs, 4) by an intramolecular redox reaction. In the present study, a cyanide ion-mediated reaction was successfully applied to the conversions of gamma,gamma-difluoro-alpha,beta-enoylsilane 1 or 2 to amide-type fluoroalkene isosteres (AM-FADIs, 5 or 6). The use of catalytic cyanide ion allowed synthesis of chiral auxiliary incorporated FADI 15b which was then subjected to a diastereoselective alpha-alkylation reaction to yield alpha-substituted FADIs 17. Furthermore, the presented amidation protocol was used for straightforward incorporation of FADI into peptidyl resin.
