The stereoselective syntheses of the naturally occurring δ-lactones (+)-tanikolide and (−)-malyngolide as well as of the unnatural (+)-enantiomer of the latter are described. Key steps in each of these syntheses were stereoselective additions of organometallic reagents to α-oxygenated ketones and olefin ring-closing metatheses.
描述了天然存在的δ-内酯(+)-tanikolide和(-)-malyngolide以及后者的非天然(+)-对映异构体的立体选择性合成。这些合成中的每个关键步骤是将有机金属试剂立体选择性地添加到α-氧化的酮和烯烃闭环复分解反应中。
