标 题:Total synthesis of prostaglandin J natural products by stereoretentive metathesis
发明人：LI JIAMING; CHEN XU; AHMED TONIA S; STOLTZ BRIAN M; GRUBBS ROBERT H
权利人:CALIFORNIA INST OF TECHN
摘要:This invention relates generally to the synthesis of Δ12-Prostaglandin J product using stereoretentive ruthenium olefin metathesis catalysts supported by dithiolate ligands. Δ12-Prostaglandin J products were generated with excellent selectivity (>99% Z) and in moderate to high/good yields (47% to 80% yield; 58% to 80% yield).

标 题 :Synthesis of scabronines and analogues thereof
发明人：DANISHEFSKY SAMUEL J; WATERS STEPHEN P
权利人:SLOAN KETTERING INST CANCER
摘要:A novel synthesis of scabronines, which are related to a broader class of angularly fused tricyclic diterpenoids known as cyathanes, is provided. Scabronine G, its methyl ester derivative, and other analogs have been shown to have neurotrophic activity. Therefore, these compounds are particularly useful in treating neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, Huntington's diseases, etc. The invention provides for the synthesis of scabronines as well as analogs thereof. Pharmaceutical compositions and method of using the inventive compounds are also provided.

标题:Synthesis of steroids
发明人：BUNES LEONARD A; JOHNSON WILLIAM S
权利人:STANFORD LELAND JUNIOR UNIV TR
摘要:Method and compounds are provided for use in the synthesis of steroids wherein a polyolefin is provided having an initiating group having a chalcogen atom in juxtaposition to a double bond, so as to be capable of bond formation to close to form a ring and having a terminating group involving pi unsaturation (a double or triple bond) conjugated to an aromatic ring. Upon acid catalysis, sigma bonds are formed through the interaction of a carbocation formed at the carbon atom bonded to the chalcogen atom and the double bond intermediate the initiating group and the terminating group, which close to form rings of a steroid nucleus, the carbocation interacting with the pi unsaturation conjugated with the aromatic group and being captured by a nucleophile present in the acidic reaction medium. The resulting steroid product may then be modified in known ways to produce known steroids.
