In one operation, metalloenamines derived from R-phenylethylamine (PEA) and a β-tetralone were treated with an electrophile followed by acrylic anhydride. The unpurified lactams were reduced to give 10b-angular benzoquinolinones (BQs).
在一种操作中,将衍生自R-苯乙胺(PEA)和β-四氢萘酮的金属烯胺用亲电试剂处理,然后用丙烯酸酐处理。还原未纯化的内酰胺,得到10b-角苯并喹啉酮(BQs)。
