bifunctional thiourea–tertiary amine as catalyst, domino Michael-type Friedel–Crafts alkylation/cyclization of β-naphthols with akylidene Meldrum’s acids was realized. The reactions afforded various enantioenriched β-arylsplitomicins with good yields (up to 99%) in moderate enantioselectivities (up to 79%).
通过采用手性双官能
硫脲-叔胺作为催化剂,实现了β-
萘酚与亚烷基Meldrum 酸的多米诺迈克尔型Friedel-Crafts 烷基化/环化。该反应以中等对映选择性(高达 79%)和良好的产率(高达 99%)提供了各种富含对映体的 β-芳基分
裂霉素。
