Details Two new nitrogenous prenylbisabolanes never before found in Lithistid sponges have been isolated from Theonella swinhoei. These new diterpenes, named amitorine A (1) and amitorine B (2), contg. a prenylbisabolane skeleton have been characterized by spectroscopic analyses, and the relative and abs. configurations of 1 and 2 were detd. by asym. synthesis of both diastereomers via the common bicyclic lactone 6 intermediate.
