The preparation of novel 1,3-dithiane derivatives, cis-and trans-2-tert-butyl-5-methylsulfonyl-1,3-dithiane, was achieved by acid-catalyzed condensation of 2-methylsulfonyl-1,3-propanedithiol with pivalaldehyde. The former dithiol was obtained from allylmethylsulfide via the Knochel-Normant brominat
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
