This manuscript describes an unprecedented and efficient synthesis of a new DPP scaffold, 2,5-dibutyl-3,6-dimethyl-1H,2H,4H,5H-pyrrolo[3,4-c]pyrrole-1,4-dione (DMDPP), containing Me groups at the 3,6-positions as a precursor to preparing 3,6-divinyl-substituted DPP compounds Subsequently, following the synthesis of DMDPP, we performed an efficient and mild C-H functionalization of the Me groups with a variety of aromatic aldehydes to synthesize the first examples of 3,6-divinyl-substituted DPP compounds in moderate to good yields.
Organic Letters published new progress about Aldol condensation. 1003-32-3 belongs to class thiazole, and the molecular formula is C4H3NOS, COA of Formula: C4H3NOS.
