  • 2-Thiazolidinone: a novel thiol protective surrogate of complete atom efficiency, a practical synthesis of (+)-biotin
    作者:Masahiko Seki、Mayumi Kimura、Masanori Hatsuda、Shin-ichi Yoshida、Toshiaki Shimizu
    DOI:10.1016/j.tetlet.2003.09.202
    日期:2003.12
    2-Thiazolidinone derivatives were shown to be novel protective surrogates of a thiol group in L-cysteine derivatives. After elaboration at the C-4 substituent, the thiol group was completely liberated by simple heating in DMF whose atom efficiency is 100%. A practical synthesis of (+)-biotin was accomplished by the use of the strategy employing 4-functionalized 2-thiazolidinone derivatives as the intermediates, allowing a synthesis of (+)-biotin in 10 steps and in 31%, overall yield. Short steps, high yield, and ease of operation of the present approach Would permit the hitherto most efficient access to (+)-biotin. (C) 2003 Elsevier Ltd. All rights reserved.
