Abstrakt: 3-(Trimethylstannyl)alanine esters containing a free amino group react with different N-benzoyloxycarbonyl amino acids in the presence of N, N′-dicyclohexylcarbodiimide to yield new dipeptides with β-(trimethylstannyl)alanine building blocks. Reactions at the stannyl group were studied in more detail in two glycyl alaninates. Their reaction with MeSnCl without solvent yields the chlorostannyl-substituted compounds. The glycyl alaninates react with two equivalents of bromine to give the dibromostannylated compounds. Graphical abstract: [Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR]
