Synthesis of isopropyl-substituted anthraquinones via Friedel–Crafts acylations: migration of isopropyl groups
Friedel-Crafts reactions of isopropyl-substituted benzenes with phthalic anhydride in the presence of aluminium trichloride, followed by cyclization of the products with strong sulfuric acid give, as expected, anthraquinones. The syntheses, however, often afford more than one anthraquinone. In some cases the isopropyl groups migrate cleanly to other ring positions; in other cases they are lost.
متن کاملSYNTHESIS OF (k) - 6,8-DIHYDROXY-3- ISOPROPYL-7-METHYLISOCHROMAN
The title isochroman ( 8 ) was synthesized as a suitable substrate for acetoxylation studies leading to an intermediate of type (4), expected to afford, on condensation with diketen, the fungal metabolite "rotiorin" type linear product (1). Cyclocondensation of alcohol (6), obtained by the reduction of ketone (5) with paraform in the presence of anhydrous aluminum chloride afforded the dim...
متن کاملDNA sequence recognition by an isopropyl substituted thiazole polyamide.
We have used DNA footprinting and fluorescence melting experiments to study the sequence-specific binding of a novel minor groove binding ligand (thiazotropsin A), containing an isopropyl substituted thiazole polyamide, to DNA. In one fragment, which contains every tetranucleotide sequence, sub-micromolar concentrations of the ligand generate a single footprint at the sequence ACTAGT. This sequ...
متن کاملIsopropyl 3,4,5-trihydroxybenzoate
In the title compound, C(10)H(12)O(5), the dihedral angle between the benzene ring is almost coplanar with the attached C(O)-O-C group [dihedral angle = 0.32 (15)°]. In the crystal, two intermolecular O-H⋯O hydrogen bonds make R(4) (4)(26) ring mofits.
متن کاملl-Tyrosine isopropyl ester
The title compound, C(12)H(17)NO(3), adopts a folded conformation with a C-C(NH(2))-C(=O)-O torsion angle of -95.9 (2)°. In the crystal, mol-ecules are linked by an O-H⋯N hydrogen bond, forming helical chains along the b-axis direction. Weak N-H⋯O and C-H⋯O hydrogen bonds are observed between the chains.
