“…Even though the classical IMCRs are not suited for generating heterocyclic compounds, new variations of the Passerini three-component reaction [ 48 , 57 ], Ugi three- and four-component reaction (U-4CR) [ 58 , 59 ], van Leusen reaction [ 60 ] and Groebke–Blackburn–Bienaymé reaction (GBBR) [ 61 , 62 , 63 , 64 ] have been explored and, indeed, IMCRs are leading today’s MCR chemistry [ 65 ]. For further information on isocyanide chemistry, the reader is directed toward further comprehensive review articles from Prof. Heravi’s group [ 66 , 67 , 68 , 69 , 70 ], Prof. Dömling’s group [ 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 ] and other extensive publications [ 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 ].…”
