In the title compound, C(18)H(24)O(4)S, the chiral bicyclo-[2.2.1]heptane group is not symmetrical due to the influence of the substituents. The angle between the three-atom bridge plane and the four-atom planes of the boat-shaped six-membered ring are 55.07 (19) and 56.24 (19)°. The bridgehead angle is 92.75 (17)°.

In the crystal structure of the title salt, (C(7)H(7)N(2)S)(2)[Mn(C(8)H(8)O(5))(2)]·6H(2)O, the heterocyclic N atom of the 2-amino-benzothia-zole mol-ecule is protonated. The Mn(II) atom (site symmetry ) has a slightly distorted octa-hedral MnO(6) coordination defined by the bridging O atoms of the bicyclo-heptane unit and four carboxyl-ate O atoms of two symmetry-related and fully deprotonated...

We have evaluated the strength of aromatic donor-acceptor interactions between dialkyl naphthalenediimide and dialkoxynaphthalene in non-polar environments. (1)H NMR, UV-vis spectroscopy and isothermal titration calorimetry were used to characterise this interaction. We concluded that the strength of donor-acceptor interactions in heptane is sufficient to drive supramolecular assemblies in this...

indandione 1 was brominated to yield 2-bromoindandione 2 which on further reacted with substituted thiocarbamides, carbamides, 2-aminothiophenols, 2-aminophenol and triazoles to furnished 3-substituted aniline-2-thia-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 3, 3-substituted aniline-2-oxa-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 4, 2-thia-5-aza-9-oxo-3,4-(3’-substitut...

We have examined the amino acid transport in B cell chronic lymphocytic leukemia and compared it with the amino acid transport in isolated B lymphocytes from human blood and tonsils. L-system transport was measured with 2-amino-2-carboxy-bicyclo (2,2,1)-heptane, which is a synthetic amino acid whose transport is limited to the L-system. Amino acid uptake was subjected to a multicomponent analys...

ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-h-phthalazin-2-yl)succinates from 2h-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-h-phthalazin-2-yl)succinates. the ionic ...

In the title polymer, [Mn(C(8)H(8)O(5))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination mode, binding to the bridging O atom of the bicyclo-heptane unit, two O atoms from corresponding carboxyl-ate groups, one carboxyl-ate O atom from a symmetry-related bridging ligand and two water O atoms. This arrangement leads to the formation of polymeric chains propagating parall...
