A practical phosgenation procedure has been devised for the preparation of isocyanates labeled with 14C, Three such isocyanates : I-tolyl isocyanaie, 4-tolyl isocyanate, and 2,4-tolylene diisocyanate (TDI) were prepared. The 14C distribution in the latter was determined by scintillation counting of
## Abstract The synthesis of selectively ^14^C‐labeled l‐tryptophan and its derivative 5‐hydroxy‐l‐tryptophan using chemical and multienzymatic methods is reported. The mixture containing [1‐^14^C[‐dl‐alanine, indole or 5‐hydroxyindole has been converted to [1‐^14^C]‐l‐tryptophan or 5′‐hydroxy‐[1‐^
