A new marine guanidine-containing compound, pulchranin A (1) was isolated from the marine sponge Monanchora pulchra. Its structure was elucidated by detailed NMR and MS analyses. The Mosher’s method did not allow determination of the absoluteconfiguration of the carbinol center in 1, but after conversion of 1 into the bis-MTPA esters of 1,3-diol 2, the same method was successfully used to solve the
