STUDIES IN POLYETHER SYNTHESIS USING POLYEPOXYDE CYCLISATIONS.

Paterson, Ian,Boddy, Ian,Mason, Ian

, p. 5205 - 5208 (2007/10/02)

The acid-catalysed directed cyclisation of mono-, di-, and triepoxy t-butyl ester derivatives is used for the asymmetric synthesis of various polyether-type fragments including a C13-C27 fragment of etheromycin.The epoxide stereochemistry is set up by Sharpless epoxidation of allylic and homoallylic alcohols.
