  Enantioselective reduction of ketophosphonates using chiral acid adducts with sodium borohydride

  摘要：

  A method for asymmetric reduction of alpha- and beta-ketophosphonates using a chiral complex prepared from sodium borohydride and D- or L-tartaric acid is developed. Reduction of alpha- or beta-ketophosphonates by these reagents led to formation of corresponding (S)- or (R)-hydroxyphosphonates. Reduction of chiral di(1R,2S,5R)-menthylketophosphonates by the chiral complex NaBH4/(R,R)-tartaric acid due to the dual compliant asymmetric induction resulted in increased stereoselectivity of the reaction and led to formation of the hydroxyphosphonates with ee 90% or higher. On the other hand, reduction of di(1R,2S,5R)-methylketophosphonates by the chiral complex NaBH4/(S,S)-tartaric acid proceeded as non-compliant dual asymmetric induction and resulted in decreased reaction stereoselectivity leading to formation of hydroxyphosphonates with similar to 45-60% ee. The developed methodology was applied to the synthesis of (R)-phosphocarnifine in multigram amounts.
