A gold (I)‐catalyzed reaction of enyne‐ethers to rapidly construct oxa‐bridged compounds via a tandem 1,2‐acyloxy migration/intramolecular oxonium formation/1,2‐rearrangement process was reported. The reaction was shown to be robust with a wide range of substitution patterns tolerated to provide the corresponding oxygen‐containing bridged products in good to excellent yields.
An interesting migration of the rigid structure of benzene was observed when propargylic esters were introduced to the cyclization chemistry of o-alkynyl(oxo)benzene. Various 8-oxabicyclo[3,2,1]octanederivatives with many functional groups could be synthesized from this efficient approach catalyzed by platinum. The high stereo- and regioselectivity involved in this transformation was also attractive
Substituted bicyclic heteroaryls and compositions containing them, for the treatment of general inflammation, arthritis, rheumatic diseases, osteoarthritis, inflammatory bowel disorders, inflammatory eye disorders, inflammatory or unstable bladder disorders, psoriasis, skin complaints with inflammatory components, chronic inflammatory conditions, including but not restricted to autoimmune diseases such as systemic lupus erythematosis (SLE), myestenia gravis, rheumatoid arthritis, acute disseminated encephalomyelitis, idiopathic thrombocytopenic purpura, multiples sclerosis, Sjoegren's syndrome and autoimmune hemolytic anemia, allergic conditions including all forms of hypersensitivity. The present invention also enables methods for treating cancers that are mediated, dependent on or associated with pi 105 activity, including but not restricted to leukemias, such as Acute Myeloid leukaemia (AML) Myelo-dysplastic syndrome (MDS) myelo-proliferative diseases (MPD) Chronic Myeloid Leukemia (CML) T-cell Acute Lymphoblastic leukaemia (T-ALL) B-cell Acute Lymphoblastic leukaemia (B-ALL) Non Hodgkins Lymphoma (NHL) B-cell lymphoma and solid tumors, such as breast cancer.
