摘要:The invention is directed to isopsoralen compound compositions that contain a variety of substitutions which yet permit their binding to nucleic acid polymers. Reaction conditions that activate these bound isopsoralens results in covalent crosslinking to the nucleic acid polymers. The resultant complex is inhibited from being a template for the template-directed enzymatic synthesis of a complementary nucleic acid polymer. Beside the isopsoralens compositions, the invention includes their synthesis, the nucleic acid complex production and detection, and the above inhibitory method of use of the isopsoralens.

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.

摘要:The invention relates to a process for the synthesis of moguisteine that is ethyl ester of (R,S)-3-[2-[(2-methoxyphenoxy)methyl]-1,3-thiazolidin-3-yl]-3-oxypropanoic acid which comprises the steps of forming a new cyclic intermediate of formula 2-[(2-methoxyphenoxy)methyl]-1,3-dioxolane (4), forming (R,S)-2-[(2-methoxyphenoxy)methyl]-1,3-thiazolidine (6) and reacting this latter with monoethylmalonic acid (7) or a salt thereof. The moguisteine of the invention is obtained in high yield and purity.
