摘要:经典的 Wolff-Kishner 还原在将羰基官能团转化为亚甲基的有机合成中起着关键作用;然而,它通常需要苛刻的反应条件,并且具有更广泛应用的策略需要进一步发展.在此,在温和条件下,用 31 个实例开发了钌催化的 Wolff-Kishner 型酮还原.该策略允许芳基酮和烷基酮具有反应性官能团,包括卤素,羟基,羧酸,不饱和官能团等.在使用水或甲醇作作为反应溶剂时,以 32% 至 95% 的收率获得了相应的亚甲基产物.

权利人:ALCHEMIA LTD
摘要:This invention relates to combinatorial libraries of potentially biologically active mainly monosaccharide compounds and to methods of preparing same. These compounds are variously functionalized, with a view to varying lipid solubility, size, function and other properties, with the particular aim of discovering a drug or drug-like compound, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of monosaccharides, variously functionalized about the sugar ring, including the addition of aromaticity and charge, and the placement of amino acid and peptide side chain units of isosteres thereof.

权利人:KURARAY CO
摘要:Polyprenols or esters thereof, which are similar in the trans and cis configurations to dolichol, or mixtures thereof are obtained from the leaves of plants belonging to the genus Pinus L. of the family Pinaceae by extraction, if necessary followed by hydrolysis, esterification or transesterification or a combination thereof. These polyprenyl compounds and mixtures thereof are useful as favorable starting materials for the synthesis of dolichol.

权利人:BOCIAN DAVID F; LINDSEY JONATHAN S; JIAO JIEYING; REGENTS OFT THE UNIVERSITY OF CALIFORNIA; UNIV NORTH CAROLINA STATE
摘要:This invention provides a procedure for growing oligomers via a stepwise process. The oligomers can include porphyrins, which have been previously shown to be attractive candidates for molecular-based information storage. The stepwise synthesis procedure requires no protecting groups, thus eliminating protection/deprotection reactions that add complexity to the process.
