The syntheses of 2-heterosubstituted atropisomeric quinazolinone phosphine ligands 7e–g have been achieved in good yield by the straightforward direct lithiation of the 2-unsubstituted quinazolinone ligand 7d followed by electrophilic substitutions.
通过2-未取代的喹唑啉酮配体7d的直接直接锂化,然后进行亲电取代,可以以高收率实现2-异取代的对映异构体喹唑啉酮膦配体7e – g的合成。
