Several approaches to the synthesis of ebelactone A 2 are described, culminating in the synthesis of the benzenesulfonate of 2-epi-ebelactone A 161. All the approaches were based on three fragments A, B and C, originally defined in general terms in, but eventually used as the aldehyde 72, the allenylsilane 3 and the aldehyde 139, respectively. They were joined, first B with C, and then B+C with A.

The present disclosure provides pharmaceutical agents, including those of the formula: (I) wherein the variables are defined herein. Also provided are pharmaceutical compositions, kits and articles of manufacture comprising such pharmaceutical agents. Methods of using the pharmaceutical agents are also provided. The compounds may be used for the inhibition or antagonism of integrins ανβ1 and/or α5β1. In some embodiments, the compounds provided herein exhibit reduced inhibitory or antagonistic activity of integrins ανβ3, ανβ5, ανβ6, ανβ8, and/or αIIbβ3.
Several synthetic routes to 3-acetonyl- and 3-(2-oxoethyl)glutarates 1–5 have been explored. The most advantageous involves, as the key steps, the conjugate addition of an appropriately substituted vinylmagnesium bromide to an alkylidenemalonicester, a bis-homologation of the resulting diester and, finally, the reductive ozonolysis of the carbon–carbon double bond. The synthesis can be satisfactorily
New pyrimidine or pyridine based compounds, compositions and methods of inhibiting the activity of glycogen synthase kinase (GSK3) in vitro and of treatment of GSK3 mediated disorders in vivo are provided. The methods, compounds and compositions of the invention may be employed alone, or in combination with other pharmacologically active agents in the treatment of disorders mediated by GSK3 activity, such as diabetes, Alzheimer's disease and other neurodegenerative disorders, obesity, atherosclerotic cardiovascular disease, essential hypertension, polycystic ovary syndrome, syndrome X, ischemia, traumatic brain injury, bipolar disorder, immunodeficiency or cancer.
