efficient one-pot synthesis of 2,5-dihydrofurans from propargyloxiranes and arylboronic acids takes advantage of sequential rhodium-gold catalysis. The transformation proceeds with center-to-axis-to-center chirality transfer and tolerates a wide variety of electron-accepting or electron-withdrawing substituents at the arylboronic acid, as well as cyclic or acyclic propargyloxiranes.
由炔丙基环氧乙烷和芳基硼酸进行的新的高效一锅法合成2,5-二氢呋喃利用了顺序的铑-金催化作用。该转变通过中心到中心到中心的手性转移而进行,并且在芳基硼酸以及环状或无环的炔丙基环氧乙烷上容许各种各样的电子接受或吸电子取代基。
