An efficient copper-catalyzed synthesis of hexahydro-1H- phenothiazines.
Hexahydro-1H-phenothiazine moieties can be synthesized by domino aziridine ring opening with o-halothiophenols followed by copper-catalyzed Goldberg coupling-cyclization with good to excellent yields. Less reactive o-chlorothiophenols are also successfully utilized for the domino reaction to synthesize phenothiazine derivatives. This methodology is successfully applied in the synthesis of pheno...
متن کامل1,3-Dibenzyl-1H-anthra[1,2-d]imidazole-2,6,11(3H)-trione
The mol-ecule of the title compound, C(29)H(20)N(2)O(3), contains four fused rings, three are six-membered rings and one is the five-membered imidazole ring. The fused-ring system is linked to two benzyl groups. The four fused rings are folded around the O=C⋯C=O direction of the anthraquinone, with a dihedral angle of 16.36 (8)° between the two terminal rings (A and D). The imidazole ring (D) i...
متن کامل7,9-Bis(hydroxymethyl)-7H-purine-2,6,8(1H,3H,9H)trione
The structure of the title uric acid derivative, C(7)H(8)N(4)O(5), from human kidney stones, is characterized by the C and O atoms of one of the two hy-droxy-methyl groups being disordered nearly equally over three different sites. In the crystal, mol-ecules are connected by a three-dimensional hydrogen-bonding scheme though they look stacked in planes nearly parallel to ([Formula: see text]04).
متن کامل1,3-Diallyl-1H-anthra[1,2-d]imidazole-2,6,11(3H)-trione
In the title compound, C(21)H(16)N(2)O(3), the fused-ring system (r.m.s. deviation = 0.067 Å) is slightly buckled at the carbonyl C atom of the anthracenyl ring system [deviation = 0.177 (1) Å] that is closer to an allyl substituent. The two allyl units lie on the same side of the fused-ring plane but are oriented in opposite directions, with N-C-C-C torsion angles of 126.9 (2) and 116.7 (2)°. ...
