Cationic Cyclization Reactions Terminated by Pinacol Rearrangements,tegy in organic synthesis. Much of the recent progress in this area stems from the development of selective electrophilic functionality for . the cyclization and complimentary nucleophilic functionality for cyclization .. Illustrative examples would be the widely employed acetal cyclization init

Mechanistic Variability in the Lewis Acid-Promoted Reactions of Aldehydes with Organostannanes,py. Using this technique, all processes involved in a rather complex manifold of reactions can be observed at low temperature. These three substrates span the range of possible behavior upon complexation with SnCl. at 1:1 stoichiometry: 2-methyl-3-benzyloxypropanal is a “strong chelator”, 3-benzylox

Synthetic and Mechanistic Studies of Lewis Acid Mediated C-C-Bond Formation,e LUMO of the carbonyl function, activating the molecule toward nucleophilic additions of enolsilanes, allylsilanes, R.Zn and Me.SiCN. The latter additions occur stereoselectively with chelation control. The sense of diastereoselectivity can be reversed using metal and protective group tuning. Group

Acylation of Alkenes and Allylsilanes,chlorides giving divinylketones which undergo the Nazarov cyclization to afford pentalenones or cyclopentenones. The acylation of alkenes by ., γ-ethylenic acyl chlorides gives cyclohexenone moieties. Applications afford a synthetic route to tricyclic carbon compounds (des-A-11-oxo or des-D-7-oxo st

Lewis Acid-Catalyzed Stereoselection on Carbohydrate Templates,hydrates are investigated as the chiral auxiliaries in alkylation reactions and in Michael additions of ester enolates. Furthermore, carbohydrates are demonstrated to be efficient chiral matrices in Lewis acid-catalyzed Diels-Alder reactions. They also effect stereoselection in a new synthesis of β-
