  一种光刻胶树脂单体及其合成方法

  摘要：

  本发明公开了一种光刻胶树脂单体，涉及光刻胶领域，其结构式如下所示：其中R1和R2分别独立的为氢、烷烃或者环烷烃；R3为氢或者甲基；n为1～8，m为1～10的整数。与其它类型的树脂单体共聚形成光刻胶树脂，能够增加了曝光区和非曝光区在碱性显影液中的溶解速度差，降低粗糙度，提高灵敏度和分辨率，有利于形成均一性良好的光刻图案，特别适用于正性光刻胶；还可以增加耐刻蚀性能；并且起始原料为天然提取的糖类，原料来源广泛，合成方法简单。

  Stereoselective preparation of O-alkoxy d-tetrose, d-pentose, 2-deoxy-d-glycero tetrose and 2,3-dideoxy-d-erythro pentose derivatives by an iterative elongation of 2,3-O-isopropylidene-d-glyceraldehyde

  摘要：

  All D-pentoses are synthesized by one-carbon chain elongation commencing with the addition of the lithium salt of ethyl ethylthiomethyl sulfoxide to 2-O-(t-butyldimethylsilyl)-3,4-O-isopropylidene-D-erythrose and D-threose, 16 and 17. The addition of the above-mentioned nucleophile to 2-deoxy-3,4-O-isopropylidene-D-glycero tetrose, 19, gave rise to 2,3-dideoxy-D-glycero pentose. The starting aldehydes, 16, 17 and 19, are easily available from 2,3-O-isopropylidene-D-glyceraldehyde, 1, and ethyl ethylthiomethyl sulfoxide. (C) 1999 Elsevier Science Ltd. All rights reserved.

• Chelation-Assisted Regioselective C−O Bond Cleavage Reactions of Acetals by Grignard Reagents. A General Procedure for the Regioselective Synthesis of Protected Polyols Having One Free Hydroxy Group

  Acetals containing a neighboring heteroatom react with the Grignard reagent in aromatic hydrocarbon solvents regioselectively. The auxiliary moiety can be hydroxy, alkoxy, or amino but not sulfur. Chelation plays a key role in directing the regioselectivity of this ring opening reaction. The reactions of acetonide derivatives of monosaccharides under these conditions afford the corresponding products having only one free hydroxy group at the specific position. Fully protected mannosamine derivative is prepared in good yield. The stereochemistry of the carbon center where auxiliary group is attached can be either syn or anti to the acetal oxygen moiety where cleavage of the C-O bond occurs. However, difference in reactivity has been found in the reaction of tris-acetonide of sorbitol with MeMgI. Regioselective ring opening of the acetal group at the anomeric carbon generates a hemiacetal which underwent further nucleophilic addition to furnish the corresponding alcohol stereoselectively.

  A simple and efficient procedure for the syntheses of all four stereoisomers of the 2,2,5-trimethyl-1,3-dioxolane-4-carbaldehydes 1a-1d has been developed. Starting with readily available aldopentose diethyl dithioacetals 2, 6, 10 and 14, the title compounds were obtained by a selective protecting group strategy and subsequent Raney-nickel reduction, followed by lead tetraacetate cleavage. This procedure allows an application on a multigram scale.
