13C NMR spectra of the three title polymers have been determined for polymers of different tacticities. Assignments to the various possible HWHT/TT and m/r dyad structures were made. These were facilitated by the use of optically active monomers in the case of 1 and 3. In the precursor polymers the

## Abstract The ^1^H and ^13^C NMR spectra of __trans__‐ and __cis__‐__tert__‐butyl 2‐methoxy‐5,6‐dihydro‐2__H__‐pyran‐6‐carboxylates (1 and 2) and 6,6′‐disubstituted 2‐methoxy‐5,6‐dihydro‐2__H__‐pyrans (3‐7) have been recorded. HH and CH coupling constants are discussed in terms of the ^1^H~6~⇄^6^
