## Abstract As asymmetric route to [^14^C]β‐hydroxycompactin 1 bearing the (__S__)‐2‐methyl‐[1‐^14^C]butanoate side chain has been developed. Methylation of [N‐[1‐^14^C]butyryl‐4‐(__S__)‐phenylmethyl‐2‐oxazolidinone 4 afforded a 95:5 mixture of diastereomeric [N‐(__S,R__)‐2‐methyl‐[1‐^14^C]butyryl]
the official ointments used as controls in both ease of mixing and in the stability of the medicated ointments. The rates of diffusion of iodine, sulfathiazole, and a mixture of benzoic and salicylic acids from the six silicone bases were compared with each other and with the rates of diffusion fro
## Abstract A synthetic procedure for 2‐^14^C‐N‐nitrosohexamethyl‐eneimine 1‐aza‐l‐nitroso‐(2‐^14^C)‐cycloheptane is presented. The starting material was 1‐^14^ C‐cyclohexanone which underwent ring expansion, reduction, and finally nitrosation. The synthesis resulted in a product in good yield (68%
