专利号:US-6268504-B1 优先权日:1997-10-15 标题 :Aryloxy-alkyl-dialkylamines 发明人:RAVEENDRANATH PANOLIL; ZELDIS JOSEPH; VID GALINA; POTOSKI JOHN R; REN JIANXIN; IERA SILVIO 权利人:AMERICAN HOME PROD 摘要:The present invention provides compounds useful in the synthesis of biologically active compounds, and processes for their production, the compounds having the formula:wherein: R1 and R2 are, independently, selected from H; C1-C12 alkyl or C1-C6 perfluorinated alkyl; X represents a leaving group; A is O or S; m is an integer from 1 to 3, preferably 2; R3, R4, R5, and R6 are independently selected from H, halogen, -NO2, alkyl, alkoxy, C1-C6 perfluorinated alkyl, OH or the C1-C4 esters or alkyl ethers thereof, -CN, -O-R1, -O-Ar, -S-R1, -S-Ar, -SO-R1, -SO-Ar, -SO2-R1, -SO2-Ar, -CO-R1, -CO-Ar, -CO2-R1, or -CO2-Ar; and Y is selected from a) the moiety:wherein R7 and R8 are independently selected from the group of H, C1-C6 alkyl, or phenyl; or b) an optionally substituted five-, six- or seven-membered saturated, unsaturated or partially unsaturated heterocycle or bicyclic heterocycle containing up to two heteroatoms selected from the group consisting of -O-, -NH-, -N(C1C4 alkyl)-, -N=, and -S(O)n-.
参考标题:General And Efficient Synthesis Of Indoles Through Triazene-Directed C-H Annulation 作者:Chengming Wang,Huan Sun,Yan Fang,Yong Huang |发布日期:2013.5.27 摘要:Unprotected Indoles Are Prepared With The Title Method, Which Has A Wide Scope For Alkynes. Excellent Regioselectivity Was Accomplished For Aryl-Alkyl And Alkyl-Alkyl Disubstituted Acetylenes. This Reaction Features An Unusual 1,2 Rhodium Migration And Ring‐contraction‐triggered Nn Bond Cleavage. It Allows Rapid Conversion Of The Reaction Products Into Several Functional Molecules.
