  An aerobic acetoxyhydroxylation of alkenes cooperatively catalyzed by organic nitrite and palladium at room temperature using clean and cheap air as the sole oxidant has been developed. Various vicinal diols, diacetoxyalkanes, and dihalogenoalkanes have been synthesized. The gram-scale synthesis has also been approached. Vicinal difluorination and dichlorolation products have also been achieved via

  DOI：10.1016/s0957-4166(00)80123-8

  日期：1993.5

  The lipase catalyzed esterifications of derivatives of propane-1,2,3-triol and butane-1,2,4-triol in organic solvents have been studied. The influence of several factors (lipase source, organic solvent, additives and structural variations in die substrates) on the selectivity have been investigated. Good levels of regio- and enantioselectivity have been achieved, providing practical methods for the synthesis of these chiral building blocks.
• Selectivity Paradigm in Lipase Reactions:  Correlating Actual and Observed Regioselectivity in Hydrolysis of Unsymmetrical Diacetates
  作者：Shrivallabh B. Desai、Narshinha P. Argade、Krishna N. Ganesh

  DOI：10.1021/jo990598x

  日期：1999.10.1

  The first simple method using labeling technique has been developed to confirm the actual and observed selectivities in the enzymatic hydrolysis of unsymmetrical diacetates and to measure the enzyme selectivity efficiency. The simple method consists of enzymatic hydrolysis of unsymmetrical diacetate followed by labeling of the hydroxyacetate formed! with. CD3COOD/DCC and enzymatic rehydrolysis of the labeled compound under the identical set of reaction conditions to estimate the amount of label retained by H-1 NMR spectroscopy. The amount of label lost directly indicates the extent of regioselective action of the enzyme.
