  A simple synthesis of 1-aminophosphonic acids from 1-hydroxyiminophosphonates with NaBH4 in the presence of transition metal compounds

  摘要：

  A new procedure has been developed for the synthesis of 1-aminophosphonic acids. Diethyl phosphonates are converted to hydroxyiminophosphonates when treated with hydroxylamine hydrochloride. Reduction of hydroxyiminophosphonates with NaBH4 in MeOH in the presence of MoO3 or NiCl2 and hydrolysis of 1- aminophosphonates gave 1-aminophosphonic acids in good yield.

• On the reaction of dialkyl acylphosphonate with 2-methylthiazolium salts.
  作者：AKIRA TAKAMIZAWA、YOSHIHIRO MATSUSHITA、HIROSHI HARADA

  Dialkyl acylphosphonate worked as an acylating agent on 2-methylthiazolium and thiazolinium salts in the presence of base, to give 2-acylidenethiazoline and thiazolidine derivatives, respectively. Dialkyl [1-aryl (alkyl)-1-dialkylphosphatomethyl] phosphonate was also isolated as a by-product in the same reaction. Dialkyl acylphosphonate afforded 2-acylidenethiazolines in better yield compared with acyl chlorides and showed on apparent affinity for carbanions. Application of diethyl benzoylphosphonate to 1, 2, 3-trimethylbenzimidazolium iodide, however, formed a dimeric salt, 1, 1', 3, 3'-tetramethyl-2, 2'-(2-phenyltrimethylene) di (benzimidazolium) diiodide in addition to 2-(1, 3-dimethylbenzimidazolin-2-ylidene) acetophenone. On the basis of the reactivity difference between the 2-methylthiazolium and 2-methylimidazolium salts and the kinetic experiments, the mechanism of the acylating reaction was proposed.

  二烷基酰基膦酸酯作为酰基化试剂，在碱存在下与2-甲基噻唑盐和噻唑啉盐反应，分别生成2-酰亚氨基噻唑啉和噻唑烷衍生物。同时，反应中还分离得到了副产物：二烷基[1-芳基（烷基）-1-二烷基膦甲基]膦酸酯。与酰氯相比，二烷基酰基膦酸酯在生成2-酰亚氨基噻唑啉时产率更高，并显示出对碳负离子的明显亲和性。然而，将二乙基苯甲酰膦酸酯应用于1,2,3-三甲基苯并咪唑盐碘时，除了生成2-(1,3-二甲基苯并咪唑啉-2-亚基)苯乙酮外，还形成了二聚盐：1,1',3,3'-四甲基-2,2'-(2-苯基亚丙基)二(苯并咪唑盐)二碘化物。基于2-甲基噻唑盐和2-甲基咪唑盐之间的反应活性差异及动力学实验，提出了酰基化反应的机理。

The simultaneous construction of up to two adjacent quaternary stereogenic centers by a catalytic asymmetric vinylogous Mukaiyama aldol reaction unites biologically and medicinally relevant entities, namely α‐hydroxy phosphonates and γ‐(hydroxyalkyl)butenolides.

  Addition reactions of nucleophilic CF3TMS to acyl phosphonates were investigated. Various acyl phosphonates reacted readily with CF3TMS in the presence of K2CO3 in DMF at rt to give 1-alkyl-2,2,2-trifluoro-1-trimethylsilyloxyethylphosphonate in 70-90% yields. When benzoyl phosphonates were used as starting material, after addition of CF3, the formed alcoholate undergoes phosphonate-phosphate rearrangement to form the acyl anion, followed by elimination of F- to give 1-aryldifluoroethenyl phosphates in 87-97% yields. As a representative example, vinylphosphate 6a was converted into 2,2-difluoro-1-phenylethanone 7 with 6 N HC1/EtOH/reflux or CAN/NaOH/MeOH/O degrees C in 82-90% yields.
