“…The combined organic layers were washed with water and dried (MgS04), and the solvent was evaporated under reduced pressure to give a white foam. The compound could be used directly for the following reaction: yield 90%; mass spectrum, m/e 396.195 (M+, caled for C24H2805 396.194); NMR 7.27 (s, 2 H, Ar ), 7.12 (s, 2 H, Ar H), 5.39 (d, 2 H, pyran 3,5-H), 3.80 (s, 6 H, OCH3), 3.20 (m, 1 3,3 4,bis(2-methoxy-5methylbenzenemethanol) (12b) was prepared from lib similarly to 12a. The product was obtained as a white foam: yield 95%; mass spectrum, m/e 424.226 (M+, caled 141.6 (s, pyran 2,6-C), 110.5 (s, pyran 3,5-C), 37.6 (d,9,16,19,heptacosa-l(25), 2,5,7,9,ll(26),21,23-octaene (2a).…”
