Abstract
The title compound (4R, 5R) (5-hydroxymethyl-2,2-dimethyl-[ 1,3 ]dioxolan-4-yl)-bis-(4-methoxy-phenyl)-methanol (C 21 H 26 O 6, M r=374.42), was synthesized and crystallized~ in the monoclinic system, space group P2 with a=9.347(1), b=10.11(1), c=11.465(2), β=114.057(2), V=989.5(2) 3, Z=2, D c=1.257mg/mm 3, F(000)=400, μ(MoKα)=0.092mm -1 , final R=0.0415, wR=0.1077 and 2369 observed reflections [I2σ(I)]. The results show that the configuration of both C(2) and C(3) are in R form, and the two OH groups are on one side of the dioxolane ring. The title compound consists of a dioxolane ring and two aromatic~ rings. Two intramolecular hydrogen bonds O(1)-H(1)…O(3) and O(4)-H(4)…O(2) are observed. In the crystal, the network is formed along the axis b by the intermolecular hydrogen bond O(1)-H(1)…O(5).
