“…The structure and absolute configuration for ignavine (CZ7H3 NO5 -H20), also isolated from this species, have been assigned as ( 48) from a single-crystal X-ray structure determination of ignavine methiodide (88). 49 The structure (89) for 'anhydroignavinol', which is the hydrolysis product of ignavine, had been determined twelve years earlier.50 However, an incorrect assignment of the molecular formula for ignavine5 had hindered the assignment of the structure of ignavine from that of its hydrolysis product.…”
