  Synthesis ofω-Substituted Alkanethiols and (Bromomethyl)methylthiomalonates

  摘要：

  Several multifunctional derivatives of methylthiomalonic acid (= 2-(thiocarboxy)acetic acid), i.e. 20a,b, 21, 22a,b, and 24, were prepared from thiols bearing a functionalized head group, i.e. from 9a,b, 12, and 16d,f (Schemes 4 and 5). The association constants of the two dithio podands 8b and 11 with K+ were determined.

  Chemo-enzymatic synthesis of chiral 2-substituted succinic acid derivatives

  摘要：

  Prochiral discrimination by the biocatalyst Alcalase(R), an enzyme preparation of subtilisin Carlsberg, was used to effect enantio- and regioselective monohydrolysis of a variety of(RS)-2-substituted succinate diesters to afford the corresponding half esters in modest to excellent enantiomeric excesses (>99%). Exploitation of malonate chemistry, as well as recycling of the unhydrolyzed isomer from the enantioselective hydrolysis, has resulted in a process which is both practical and economical.
