  An improved and novel approach to macrolactonisation using di-tert-butyl dicarbonate

  摘要：

  A new, facile, mild and simple method for the synthesis of macrolides was achieved from omega- hydroxy acids using di-tert-butyl dicarbonate ( Boc(2)O), a cheap and commercially available reagent. A wide range of substrates were tested and give good yield of lactones. The effect of various simple bases on the yield of the macrolactonisation reaction was also studied.
