It is a liquid at room temperature with a strong odor of ammonia and is strongly basic compared to most secondary amines. Azetidines do not occur as frequently in nature and have been studied far less than closely related chemical compounds such as pyrrolidine and β-lactam. Natural occurrenceAzetidine and its derivatives are relatively rare structural motifs in natural products. Notably, they are a key component of mugineic acids and penaresidins. Perhaps the most abundant azetidine containing natural product is azetidine-2-carboxylic acid, a non-proteinogenic homolog of proline. See also
