A rapid and efficient enantiospecific synthesis of the functionalized ABC-ring system of tetranortriterpene dumsins and their analogues
摘要:
A rapid and enantiospecific synthesis of the ABC ring system of tetranortriterpene dumsin and its analogues, starting from the readily available monoterpene (R)-carvone employing two RCM reactions as key steps, is described. (C) 2008 Elsevier Ltd. All rights reserved.
