Environmentally benign and highly atom economic catalytic Friedel-Crafts alkylation reaction and diastereoselective C-O bond formation reaction has been developed. The scope and generality of this reaction was amply illustrated by synthesis of chromazonarol, hongoquercin A and B and analogues thereof.
已开发出环境友好且具有高原子经济性的催化 Friedel-Crafts 烷基化反应和非对映选择性 CO 键形成反应。该反应的范围和一般性通过 chromazonarol、hongoquercin A 和 B 及其类似物的合成得到充分说明。

A scalable, divergent synthesis of bioactive meroterpenoids has been developed. A key component of this work is the invention of "borono-sclareolide", a terpenyl radical precursor that enables gram-scale preparation of (+)-chromazonarol. Subsequent synthetic operations on this key intermediate permit rapid access to a variety of related meroterpenoids, many of which possess important biological activity.
