标 题:Synthesis of 13-alkyl-gon-4-ones
发明人:HUGHES GORDON ALAN; SMITH HERCHEL
权利人:SMITH HERCHEL
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.

标 题:Process for the preparation of 9-β-anomeric nucleoside analogs
发明人:GUPTA PRANAB K; MUNK STEPHEN A
权利人:ASH STEVENS INC
摘要:A process for substantially enhancing the regio and stereoselective synthesis of 9-β-anomeric nucleoside analogs is described. The introduction of the sugar moiety onto a 6-substituted purine base was preformed so that only the 9-β-D- or L-purine nucleoside analogs were obtained. This regio and stereoselective introduction of the sugar moiety allows the synthesis of nucleoside analogs and in particular 2′-deoxy, 3′-deoxy, 2′-deoxy-2′-β-fluoro and 2′,3′-dideoxy-2′-β-fluoro purine nucleoside analogs in high yield without virtually any formation of the 7-positional isomers. The compounds are drugs or intermediates to drugs.

标题:Synthesis of graphene nanoribbons from monomeric molecular precursors bearing reactive alkyne moieties
发明人:RUBIN YVES; JORDAN ROBERT S; LI YOLANDA L; MCCURDY RYAN D; KERVYN DE MEERENDRÉ SIMON
权利人:UNIV CALIFORNIA
摘要:A method of forming a graphene nanoribbon includes: 1) providing monomeric precursors each including an alkyne moiety and at least one aromatic moiety bonded to the alkyne moiety; 2) polymerizing the monomeric precursors to form a polymer; and 3) converting the polymer to a graphene nanoribbon.
