• Transition‐Metal‐Free Cross‐Coupling by Using Tertiary Benzylic Organoboronates
  作者：Mitsutaka Takeda、Kazunori Nagao、Hirohisa Ohmiya

  DOI：10.1002/anie.202010251

  日期：2020.12.7

  The transition‐metal‐free cross‐coupling of alkyl or aryl electrophiles by using tertiary benzylic organoboronates is reported. This reaction involves the generation of tertiary alkyl anions from organoboronates in the presence of an alkoxide base and then their substitution reactions. This protocol allows the simple and efficient construction of quaternary carbon centers.

  据报道，使用叔苄基有机硼酸酯可实现烷基或芳基亲电试剂的无过渡金属交叉偶联。该反应包括在醇盐碱的存在下由有机硼酸酯生成叔烷基阴离子，然后进行取代反应。该协议允许简单有效地构建季碳中心。

  A new indolocarbazole compound, NB-506 (1), modified at the glucose group yielded a beta-D-glucopyranoside, J-107,088 (2), which showed potent anticancer activity. A beta-D-ribofuranoside, J-109,534 (3), was found to be 6 times more potent than J-107,088 at inhibiting topoisomerase I.

  日期：2011.6.3

  Dehydrative glycosylation reactions using 2-deoxy- and 2,6-dideoxy-sugar donors promoted by a combination of 3,3-dichloro-1,2-diphenylcyclopropene and tetrabutylammonium iodide (TBAI) are described. The reactions are α-selective and proceed under mild conditions at room temperature without the need for special dehydrating agents. The reaction is shown to be effective with a number of glycosyl acceptors

• Synthesis of 2-deoxy-α- and -β-<scp>D</scp>-arabino-hexopyranosyl phosphonic acids and related compounds; analogues of early intermediates in the shikimate pathway

  Treatment of 1-O-acetyl-3,4,6-tri-O-benzyl-2-deoxy-D-arabino-hexopyranose 18 with trimethyl phosphite in the presence of trimethylsilyl triflate gave a separable mixture of dimethyl (3,4,6-tri-O-benzyl-alpha-D-arabino-hexopyranosyl)phosphonate 19 (35%) and the beta-anomer 20 (60%). The diethyl analogue of compound 20 could be prepared stereoselectively from tributyl (3,4,6-tri-O-benzyl-2-deoxy-beta-D-arabino-hexopyranosyl)stannane 21 and diethyl chlorophosphate.Reaction of 1,3,4,6-tetra-O-acetyl-2-deoxy-D-arabino-hexopykanose 23 with trimethyl phosphite and trimethylsilyl triflate gave dimethyl (3,4,6-tri-O-acetyl-2-deoxy-alpha-D-arabino-hexopyranosyl)phosphonate 25 and the beta-anomer 27 with some alpha-selectivity. Deprotection of compounds 25 and 27 gave the phosphonic acids 11 and 12 respectively. The esters 25 and 27 could be converted into methyl 3,4,6-tri-O-acetyl-2-deoxy-1-(dimethoxyphosphoryl)-beta-D-arabino-hexopyranoside 31 by free-radical bromination followed by methanolysis, and diethyl [3,4,6-tri-O-(tert-butyldiphenylsilyl)-2-deoxy-D -arabino-hex-1-enopyranosyl)phosphonate 33 was prepared by interaction of the 1-lithioglucal with diethyl chlorophosphate.Metallation of stannane 21 and reaction with methyl chloroformate gave methyl 2,6-anhydro-4,5,7-tri-O-benzyl-3-deoxy-D-gluco-heptonate 35 which could be alkylated with tert-butyl bromoacetate to give, after deprotection, 3,7-anhydro-3-carboxy-2,4-dideoxy-D-gluco-octonic acid 14.
