Aminomethylation of lambertianic acid under classical conditions ol. the Ma
nnich reaction anti reactions of lambertianic acid and its esters with meth
ylenediamines and acetyl chloride lead to formation of the corresponding 16
-aminomethyl derivatives. Structurally related products are also formed by
reductive amination of 16-formyllambertianic acid.
