Whereas simple 4,4Π-bi(1,3-dioxanyl)s 16 and 19 displayed little conformational preference at the inter-ring bond, their derivatives 4 and 13, with equatorial methyl groups in the 5and 5Π-positions, each showed a strong conformational preference to populate a conformation with a gauche arrangement o
