Differential carbosubstitution resulted from stepwise triflation and coupling in spiro[4,4]-nonane-1,6-dione. Catalytic hydrogenation of the 1,6-diphenyl-1,6-diene gave the cis,cis-disubstituted spirane. Metal hydride reduction of intermediate monoketone gave mainly the cis-alcohol.
P烯三氟甲磺酸酯中的碳取代可通过Pd催化与甲锡化或锌化的芳烃偶联而实现。碳的差异取代是由螺[4,4]-壬烷-1,6-二酮中的逐步tri化和偶联引起的。1,6-二苯基-1,6-二烯的催化加氢得到顺,顺-二取代的螺烷。中间体一酮的金属氢化物还原主要得到顺式-醇。
