2-Isobutyl-6-phenylimidazo[2,1-b][1,3,4]thiadiazole
In the title compound, C(14)H(15)N(3)S, the imidazo[2,1-b][1,3,4]thia-diazole fused-ring system is close to planar, with a maximum deviation of 0.042 (1) Å, and the dihedral angle between it and the phenyl ring is 24.21 (6)°. The isobutyl group is disordered over two sets of sites in a 0.899 (9):0.101 (9) ratio. In the crystal, weak aromatic π-π stacking inter-actions involving the imidazole an...
متن کامل2-Isobutyl-6-(4-methoxyphenyl)imidazo[2,1-b][1,3,4]thiadiazole
In the title compound, C(15)H(17)N(3)OS, the dihedral angle between the statistically planar imidazo[2,1-b][1,3,4]thia-dia-zole fused-ring system (r.m.s. deviation = 0.002 Å) and the methyoxbenzene ring is 4.52 (6)°. In the crystal, mol-ecules are arranged into columns and stacked down the a axis. The crystal structure is stabilized by weak C-H⋯π and π-π inter-actions [centroid-centroid separat...

In the crystal structure of the title compound, C(18)H(18)Br(2)O(2), the two benzene rings of the bridged biphenyl unit are twisted by 38.0 (1)°.
متن کامل2-Isobutyl-2-phosphabicyclo[3.3.1]nonane 2-selenide
The title compound, C(12)H(23)PSe, represents the first structure of a phosphine containing the bicyclic 2-phospha-bicyclo-[3.3.1]nonane (VCH) unit. It contains two chiral centres per mol-ecule which can be either R,R- or S,S and crystallizes as a centrosymmetric, racemic micture of the enanti-omers. The P-Se bond distance of 2.1360 (16) Å is typical for these compounds. The Tolman cone angle (...
متن کاملBiosynthesis of phlorisovalerophenone and 4-hydroxy-6-isobutyl-2-pyrone in Escherichia coli from glucose
BACKGROUND Type III polyketide synthases (PKSs) contribute to the synthesis of many economically important natural products, which are typically produced by direct extraction from plants or synthesized chemically. For example, humulone and lupulone (Fig. 1a) in hops (Humulus lupulus) account for the characteristic bitter taste of beer and display multiple pharmacological effects. 4-Hydroxy-6-me...
