One‐pot Synthesis,Crystal structure,and Bioactivity of N‐Phenoxyacetyl‐2,4,5‐trisubstituted‐1,3‐oxazolidines |
| |
Abstract: | N‐phenoxyacetyl‐1,3‐oxazolidine derivatives were synthesized by the cyclization and acylation with β‐amino alcohol, ketone, and phenoxyacetyl chloride as the starting materials. All compounds were characterized by IR, 1H NMR, 13C NMR, ESI‐MS, and elemental analysis. The configuration of 4a was determined by X‐ray crystallography. The preliminary biological tests showed that all products could protect soybean against injury caused by 2,4‐D butylate to some extent. |
