  酯汽车光还原剂六价六甲基磷三酰胺（HMPT）

  摘要：

  在光化学中使用HMPT作为溶剂可实现有效的光还原。烷基酯，尤其是不吸收性的乙酸烷基酯，以优异的产率被光还原成烷烃。在后一种情况下，质子化剂是必要的。许多例子说明了该反应的一般性和便利性。这种光还原涉及电子从HMPT转移到酯。

• A selectivity study of activated ketal reduction with borane dimethyl sulfide
  作者：Birgit Bartels、Roger Hunter

  DOI：10.1021/jo00076a041

  日期：1993.11

  A chemo- and regioselectivity study of the reagent combination BH3.SMe2/TMSOTf for ketal reduction has been undertaken. It has revealed that simple 1,3-dioxanes reduce cleanly at low temperature in CH2Cl2 while simple 1,3-dioxolanes may give complete ring cleavage and dimerization products. A study of reduction of 4-substituted 1,3-dioxolanes has revealed a solvent-directed regioselectivity which in THF favors the secondary protected derivative. A mechanism is postulated to account for the selectivities based on recent thinking on acetal substitution reactions.
• Preparation of dehydroepiandrosterone, testosterone and progesterone antigens through 7-carboxymethyl derivatives: Characteristics of the antisera to testosterone and progesterone
  作者：Danièle Duval、Bernard Desfosses、Romeo Emiliozzi

  DOI：10.1016/0039-128x(80)90037-9

  日期：1980.3

  Dehydroepiandrosterone, testosterone and progesterone 7-carboxymethyl derivatives were prepared: 7 alpha and 7 beta epimers were separated and coupled to bovine serum albumin. Preliminary studies of the antisera induced by these antigens showed that they have high affinity and good specificity.
