Syntheses of enantiopure aliphatic secondary alcohols and acetates by bioresolution with lipase B from Candida antarctica.
The lipase B from Candida antarctica (Novozym 435®, CALB) efficiently catalyzed the kinetic resolution of some aliphatic secondary alcohols: (±)-4-methylpentan-2-ol, (±)-5-methylhexan-2-ol, (±)-octan-2-ol, (±)-heptan-3-ol and (±)-oct-1-en-3-ol. The lipase showed excellent enantioselectivities in the transesterifications of racemic aliphatic secondary alcohols producing the enantiopure alcohols ...
متن کاملPlatinum- and gold-catalyzed rearrangement reactions of propargyl acetates: total syntheses of (-)-alpha-cubebene, (-)-cubebol, sesquicarene and related terpenes.
Propargyl acetates, in the presence of catalytic amounts of late transition-metal salts such as PtCl(2) or AuCl(3), represent synthetic equivalents of alpha-diazoketones. This notion is corroborated by a concise approach to various sesquiterpene natural products starting from readily available substrates. Specifically, (+)-carvomenthone (17) is converted into propargyl acetate (S)-26 by a seque...
متن کاملSurface properties of water soluble maltodextrin, starch acetates and starch acetates/alkenylsuccinates
Surface and interfacial tensions with hexadecane were measured for water soluble maltodextrin and starch ester solutions in order to determine heir potential as stabilizers or emulsifiers. The surface tension for an acid hydrolysed starch (maltodextrin) initially declined with concentration nd then reached an equilibrium value of 56 mN/m at 20–40 wt.%, suggesting that hydrated starch has this s...
متن کامل4-Iodo-2-methylaniline
In the mol-ecule of the title compound, C(7)H(8)IN, the methyl C, I and N atoms lie in the benzene ring plane. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules in a stacked arrangement along the a axis.
