New discoveries in chemical research and development in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 10323-20-3, Name is D-Arabinose, molecular formula is C5H10O5. In an article, author is ABBOUD, KA,once mentioned of 10323-20-3, Recommanded Product: 10323-20-3.
{3aR-[3a-alpha,4-alpha,5-beta(R*),6-alpha,6a-alpha]}-Methyl 4-{[(1,1-dimethylethyl)dimethylsilyl]oxy}tetrahydro-6-hydroxy-alpha-(1-hydroxycyclohexyl)-2,2-dimethyl-4H-cyclopenta-1,3-dioxole-5-acetate, C23H42O7Si, M(r) = 458.75, monoclinic, P2(1), a = 11.537 (2), b = 8.552 (2), c = 13.916 (4) angstrom, beta = 92.39 (2)-degrees, V = 1371.8 (5) angstrom 3, Z = 2, D(x) = 1.11 g cm-3, Mo K-alpha, lambda = 0.71069 angstrom, mu = 1.2 cm-1, F(000) = 500, T = 298 K, R = 0.0564 and wR = 0.0638 for 1475 reflections [I greater-than-or-equal-to 3-sigma(I)]. Crystal chirality was assigned to correspond to the known chirality of the precursor compound. The cyclopentane ring exhibits an envelope conformation (E1) where C(1) occupies the flap position [0.58 angstrom from the plane of C(2), C(3), C(5) and C(6)]. The dioxole ring is in an unusual planar conformation. This planarity may be partially attributed to the disorder of the C-(CH3)2 moiety at the C(4) position. The cyclohexyl ring exhibits a chair conformation (4C1) where atoms C(8) and C(11) are 0.61 angstrom and -0.66 angstrom, respectively, from the plane of atoms C(9), C(10), C(12) and C(13).
