In this latter case, the strategic combination of chemoselective carbonyl addition and SmI(2)/Pd(0)-promoted cyclization provides ready and convenient stereocontrolled access to functionalized cyclopentanols from unprotected 1,5-dicarbonyl starting materials. The analogous formation of cyclohexanols is limited by

    Aliphatic, cyclic, and aromatic benzoate-protected γ-hydroxy enol ethers were prepared from α-brominated dioxolanes by a three-step reaction procedure and a one-pot protocol involving Grignard reagent formation, ring-opening, and final benzoate protection. Additionally, tert-butyldiphenylsilyl, acetate, and 4,4′-dimethoxytrityl were also successfully used as alternative protecting groups.

    Twenty-one derivatives of 4-acyloxy-1-(1, 3-dioxolan-2-ylmethyl) piperidines (2) and their quaternary salts (6) were synthesized and tested for anticholinergic activities. The piperidine derivatives (2) exhibit moderate activities. Among the quaternary salts (6), the trans-isomers were always more active than the corresponding cis-isomers.
