The total syntheses of (R)-argentilactone (five steps, 25% overall yield) and (R)-goniothalamin (three steps, 61% overall yield) have been described through the enantioselective catalytic allylation of aldehydes (including a propargylic aldehyde) which provided a rapid access to these natural products that display very interesting biological activities.
已通过醛(包括炔丙基醛)的对映选择性催化烯丙基化描述了(R)-精氨酸内酯(五个步骤,总收率25%)和(R)-角硫胺素(三个步骤,总收率61%)的总合成,其中提供了对具有非常有趣的生物活性的天然产品的快速访问。
