Conformational analysis of oligo-1,3-dioxanylmethanes

Stereoselective synthesis of a series of 1,3-dioxan-4-ylmethanes 1-9 has been achieved by use of solely substrate-based asymmetric induction. The simple C2-symmetric bis(dioxanyl)methane 1 has a greater than 99% conformational preference at the two inter-ring bonds for the conformation 1a. The homologous structures 3-9 contain up to five dioxanylmethane units, maintaining a high conformational preference in each of the bis(dioxanyl)methane units. Thus, these flexible compounds reach a conformational preference in excess of 90% over up to eight rotatable interring bonds. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.

Stereoselective synthesis of skipped polyols by substrate-directed asymmetric induction

(formula presented) A series of C2-or σ-symmetric oligo-1,3-dioxanylmethanes, 2-5, have been prepared using a bidirectional approach. In bidirectional syntheses of meso compounds, only substrate-based asymmetric induction could be applied. 1,3-
