摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.

标题:Synthesis of crystalline porous solids in ammonia
发明人：GARCES JUAN M; MILLAR DEAN M; HOWARD KEVIN E
摘要:A process of preparing a crystalline porous solid selected from silicas and metallosilicates, such as, aluminosilicate zeolites or clathrasils. The process involves preparing a reaction mixture containing ammonia; water in a controlled concentration; a (hydrocarbyl)ammonium polysilicate hydrate salt; a mineralizer, such as ammonium fluoride; optionally, a source of a metal oxide, such as aluminum nitride; and optionally, a source of a charge-balancing cation or a structure directing agent; and maintaining the mixture at a temperature and for a time so as to produce the crystalline porous solid. A novel silica which is isostructural with zeolite P1 is prepared. Also prepared are a novel silica which is isostructural with zeolite beta and a novel TMA sodalite having a silica/alumina molar ratio between 12 and about 20.
