Synthesis of δ--α-aminoadipoyl--cysteinyl--allylglycine, and eight deuterated analogues, substrates for the investigation of the mechanism of action of isopenicillin n synthase.
摘要:
The synthesis of delta-L-alpha-aminoadipoyl-L-cysteinyl-D-allylglycine (1a) from its component amino acids is described, along with the synthesis of eight analogues (1b-i) specifically deuterated at C-3 and/or C-5 of the allylglycine residue.
