A concise synthesis of maleic anhydride and maleimide natural products found in Antrodia camphorata
摘要:
Recently, the natural products maleic anhydride I and maleimides 2 and 3 have been isolated from the mycelium of Antrodia Camphorata, each displaying activity in LLC cell lines. We describe a concise synthesis of each of these natural compounds utilizing C-C cross-coupling methodology, namely, the Negishi and Suzuki reactions. This efficient and high yielding synthesis is convergent lending itself to production of medicinal analogues. (c) 2007 Elsevier Ltd. All rights reserved.

This invention relates to pyrrolopyrimidine comprising compounds that may be useful as inhibitors of Mitogen-activated Protein Kinase Kinase Kinase Kinase-4 (MAP4K4). The invention also relates to the use of these pyrrolopyrimidine comprising compounds, for example in a method of treatment. There are also provided processes for producing compounds of the present invention and method of their use. In particular, the present invention relates to compounds of formula (I).
Substituted spirocyclic amines of structural formula (I) are selective antagonists of the somatostatin subtype receptor 5 (SSTR5) and are useful for the treatment, control or prevention of disorders responsive to antagonism of SSTR5, such as Type 2 diabetes, insulin resistance, lipid disorders, obesity, atherosclerosis, Metabolic Syndrome, depression, and anxiety.
An efficient dehydrogenativeDiels–Alder (DHDA) reaction of prenylderivatives with 2,3‐dichloro‐5,6‐dicyanobenzoquinone (DDQ) has been developed under mild conditions, leading to a series of cyclohexene derivatives with good to excellent yields and excellent diastereoselectivity.
