The CâC bond fragmentation of carbocycles has been developed as a new method for the divergent synthesis of dendrimers. The scope of this reaction was examined with the preparation of six first generation dendrimers from structurally diverse and readily available fragmentation precursors. By pairing the fragmentation with a thio-Michael reaction, the preparation of a [G4]-ene24 dendrimer has been achieved.

Organic dye-catalyzed radical ring expansion reaction
Herein, we reported an attractive method for synthesizing medium-sized rings that are catalyzed by erythrosine B under fluorescent light irradiation. This synthetic approach featured mild conditions, a facile procedure, a broad substrate scope, and moderate-to-good yields.
在这里,我们报道了一种有吸引力的方法,用于合成由赤藓红 B 在荧光光照射下催化的中等大小的环。这种合成方法具有条件温和、程序简便、底物范围广、产率适中等特点。
