                                摘要:
                                The preparation of three carbonates and two carbamates of norethisterone (17 alpha-ethynyl-17 beta-hydroxyestr-4-en-3-one) are described. Due to instability of the carbonates and the very low solubility of the carbamates these compounds could not be submitted to biological testing.
