An easy approach to chiral non-racemic 6-(furan-3-yl)-5,6-dihydro-pyran-2-ones
摘要:
Chiral non-racemic 6-(furan-3-yl)-pyran-2-one derivatives, key-intermediates in the preparation of compactin, manoalide and cacospongionolide subunits, are easily accessible through a rapid and convenient six-step sequence. (C) 1998 Elsevier Science Ltd. All rights reserved.
