Synthetic routes to N-1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutyl}-N,N-dimethylamine (sibutramine) 1 and its demethylated and hydroxylated human metabolites N-1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutyl}-N-methylamine 2, 1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutylamine 3, 4-amino-4-[1-(4-chlorophenyl)cyclobutyl]-2-methylbutan-1-ol 4 and c-3-(1-amino-3-methylbutyl)-3-(4-chlorophenyl)cyclobutan-r-1-ol 5a are described. Key steps are tandem Grignard–reduction reactions on 1-(4-chlorophenyl)cyclobutanecarbonitrile 7 and its 3-(tetrahydropyran-2-yloxy)-substituted analogue 14 and a convenient one-pot conversion of 4-chlorophenylacetonitrile 6 into the 3-hydroxycyclobutanecarbonitrile 13.

prepared from 1,3-dibromo-2-propanol in a two-step sequence involving hydroxyl protection and sodium hydride-induced dehydrobromination. Indium-mediated allylation of aldehydes, ketones, and sulfonimines with 2-(alkoxy)propenyl bromides furnishes the corresponding homoallylic alcohols and sulfonamines in good yields. The products can be easily transformed into β-hydroxyketones and esters, as well
Tetrahydropyranyl protecting group. II. 3-Bromo-2-(tetrahydropyran-2-yloxy)propene, a masked acetonyl bromide

It is shown that the sodium hydride (in dimethyl formamide) induced elimination of hydrogen bromide from 1,3-dibromo-2-(tetrahydropyran-2-yloxy)propane (3) can be considered to result in the in situ formation of 3-bromo-2-(tetrahydropyran-2-yloxy)propene (4). When generated in this manner, 4 was shown to function as a masked acetonyl bromide of considerable utility. Under similar conditions, 1,3-d
