Preparation of n n' 7 thioctylurea the sulfide predecessor of the alkaloids diptocarpidine and diptocarpiline

, : Preparation of n n' 7 thioctylurea the sulfide predecessor of the alkaloids diptocarpidine and diptocarpiline. Khimiya Prirodnykh Soedinenii (5): 742-744

Diptocarpidine and diptocarpiline are produced by Diptychocarpus strictus. A convenient method was developed on the basis of 6-heptenic acid for the synthesis of the key sulfide predecessors of the alkaloids. TLC and IR and H1 NMR spectra were used to study the synthesis products.
