| Summary: | Acylation of N‐(2, 6‐Dimethylphenyl)‐α‐alanine Methylester with sp‐hybridized Carbonic Acid Derivatives . The title compound 5 reacts with isocyanates and isothiocyanates to yield the substituted imidazolidinones 7 and 8 , respectively, whereas with chlorosulfonyl isocyanate the open chained urea 9 is formed. Cyanation of 5 takes place with phenyl cyanate and cyanogene bromide. Consecutive reactions of the primary products are described. |
