Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Yan, Jun, once mentioned the application of 4701-17-1, Name is 5-Bromothiophene-2-carbaldehyde, molecular formula is C5H3BrOS, molecular weight is 191.05, MDL number is MFCD00005432, category is indole-building-block. Now introduce a scientific discovery about this category, SDS of cas: 4701-17-1.
Lewis acid-catalyzed cyclodimerization of 1-substituted-3-arylvinylindoles leading to highly functionalized fused cyclopenta[b]indoles
An unexpected Lewis acid-catalyzed [3+2] cycloaddition reaction of 1-substituted-3-arylvinylindoles was revealed when we studied the chemistry of donor-acceptor cyclobutanes and 1-substituted-3-arylvinylindoles. This method provides a simple, efficient route to synthesis of highly functionalized fused cyclopenta[b]indoles in good to excellent yields with high diastereoselectivity under mild reaction conditions.
