要旨
C-Acylations of polymer-supported 2-phosphoranylidene acetates ("linker reagents") with protected amino acids yielded 2-acyl-2-phosphoranylidene acetates as flexible intermediates for the C-terminal variation of carboxylic acids: peptidyl-2,3-diketoesters, peptidyl vinyl ketones, peptidyl-2-ketoaldehydes, and 1,3-diamino-2-hydroxy-propanes were obtained as products.
