标 题:Using stereoretention for the stereoselective formation of e-macrocycles with Ru-based olefin metathesis catalysts
发明人：AHMED TONIA S; MONTGOMERY T PATRICK; GRUBBS ROBERT H
权利人:CALIFORNIA INST OF TECHN
摘要:This invention relates generally to the synthesis of E-macrocycles using stereoretentive ruthenium olefin metathesis catalysts supported by dithioiate ligands. Macrocycles were generated with excellent selectivity (>99% E) and in moderate to high/good yields (47% to 80% yield; 58% to 80% yield) from diene starting materials bearing two E-olefins or bearing one E-olefin and one terminal olefin, A variety of rings were constructed, ranging from 12- to 18-membered macrocycles, including the antibiotic recifeiolide. The invention has utility in the fields of organometallics and organic synthesis.

标题 :Highly efficient synthesis of Z-macrocycles using stereoretentive, ruthenium-based metathesis catalysts
发明人：AHMED TONIA S; GRUBBS ROBERT H
权利人:CALIFORNIA INST OF TECHN
摘要:A highly efficient, Z-selective ring-closing metathesis system for the formation of macrocycles using a stereoretentive, ruthenium-based catalyst supported by a dithiolate ligand is reported. This catalyst is demonstrated to be remarkably active as observed in initiation experiments showing complete catalyst initiation at −20° C. within 10 min. Using easily accessible diene starting materials bearing a Z-olefin moiety, macrocyclization reactions generated products with significantly higher Z-selectivity in appreciably shorter reaction times, in higher yield, and with much lower catalyst loadings than in previously reported systems. Macrocyclic lactones ranging in size from twelve-membered to seventeen-membered rings are synthesized in moderate to high yields (68-79% yield) with excellent Z-selectivity (95%-99% Z).

摘要:The preparation of 13-methylgon-4-enes and novel 13-polycarbonalkylgon-4-enes by a new total synthesis is described. 13-Alkylgon-4-enes having progestational, anabolic and androgenic activities are prepared by forming a tetracylic gonane structure unsaturated in the 1,3,5(10),9(11) and 14-positions, selectively reducing in the B- and C-rings, and converting the aromatic A-ring compounds so-produced to gon-4-enes by Birch reduction and hydrolysis.

发明人：YAMASHITA HIROSHI; TANAKA MASATO
权利人:AGENCY IND SCIENCE TECHN
摘要:There is disclosed a method of preparing cyclic silyl enol ethers (1-oxa-2-sila-5-cyclohexenes), comprising reacting a silacyclobutane with an acid halide in the presence of a palladium catalyst and an organic base. There is also disclosed novel cyclic silyl enol ethers obtained by the above method. The above cyclic silyl enol ethers belong to a new class of silyl enol ethers which are useful in the production of medicines and agricultural chemicals, and they can be used as intermediates of fine chemicals or as various reagents for fine synthesis.
