Lewis acid mediated diastereoselective allylation of 3- menthyloxycarbonyl-5,6-dihydropyridin-4-ones

Sakurai allylation of menthyl enoates 5a-c afforded adducts 7a-c with low to excellent facial selectivity, depending on the Lewis acid employed to promote this 1,4-nucleophilic addition of allyltrimethylsilane. A chelated model was assumed to explain the

Lewis acid-promoted asymmetric conjugate allylation of N-acyl-2,3-dihydro-4-pyridones induced by intramolecular π interactions

Lewis acid-promoted conjugate addition reaction of an allylsilane to a series of the chiral 8-arylmenthol-derived N-acyl-2,3-dihydro-4-pyridones leads to the 2-allyl-4-piperidones with moderate to high levels of asymmetric induction, indicating π-stacking contribution to chirality control. This methodology was applied to the asymmetric synthesis of (-)-N-methylconiine. Copyright (C) 1996 Elsevier Science Ltd.

Alkynylation of Thiolactams. New Synthesis of α-Substituted Pyrrolidine and Piperidine Alkaloids

Alkynylation of S-alkylthioamidium salts of thiolactams with lithium acetylides followed by reduction with LiAlH4 provided α-alkynylazacycloalkanes, which on reduction, or hydroboration followed by oxidation, gave α-substituted pyrrolidine and piperidine alkaloids.
