This disclosure relates to ester compounds derived from neo-alcohol, lubricating oil base stocks comprising such ester compounds, lubricating oil compositions comprising such ester compounds, and method for making such compounds and/or base stocks. The lubricating oil base stocks comprising the ester compounds exhibit desirable lubricating properties such as polarity and oxidation stability.

The first example of carboxy group assisted, remote-selective C(sp2 )-H activation with a PdII catalyst has been developed and proceeds through a possible κ2 coordination of the carboxy group, thus suppressing the ortho-C-H activation through κ1 coordination. Besides meta-C-H olefination, direct meta-arylation of hydrocinnamic acid derivatives with low-cost aryl iodides has been achieved for the first
of 3-phenyl-propionic acids, dimerization led to by-products which can be considered as dimeric indanones. The proton NMR spectra of these compounds exhibit pronounced scalar couplings over up to seven bonds. A series of structures of the above type were investigated, and their NMR spectroscopic behaviour is discussed.

The invention relates to novel compositions and to methods for the pulsed administration of compositions to a patient or to cells in vitro for the treatment of human blood disorders. Compositions contain chemical compounds that stimulate the expression of fetal hemoglobin and/or stimulate the proliferation of red blood cells, white blood cells and platelets in patients and ex vivo for reconstitution of hematopoiesis in vivo. These methods are useful to treat or prevent the symptoms associated with anemia, sickle cell disease, thalassemia, blood loss, and other blood disorders. The invention also relates to methods for the pulsed administration of compositions to patients for the treatment and prevention of cell proliferative disorders including deficiencies such as cytopenia and malignancies and for expansion of cells for hematopoietic transplantation. Pulsed administration has been shown to be more effective than continuous therapy in patients tested.
