Verdoppelungsreaktionen beim Ringschluss von Peptiden IV. Die stereoisomeren Cyclo??phenylalanyl??glycyl??glycyl??phenylalanyl??glycyl??glycyle und die …
Abstract Cyclisation of active esters of the racemic tripeptides glycyl-glycyl-DL- phenylalanine and glycyl-DL-phenylalanyl-glycine as well as of the hexapeptide glycyl- glycyl-DL-phenylalanyl-glycyl-glycyl-DL-phenylalanine (unidentified mixture of diastereoisomers) has yielded as main product the meso-cyclohexapeptide, cyclo-glycyl-L- phenylalanyl-glycyl-glycyl-D-phenylalanyl-glycyl (IV). This is proven by comparison of the ...
