Recherches en vue de la synthèse de barbituriques organostannylés, II
摘要:
Abstract(a) The synthesis of 2,4,6‐trioxo‐1, 3‐di‐tributylstannyl‐hexahydropyrimidine is described.(b) Trimethyltin hydride is found to add in a photochemical reaction to the terminal double bond of diethyl allyl malonate and allyl methyl malonate, giving respectively diethyl‐(3‐trimethylstannylpropyl)‐ (1) and diethyl‐(3‐trimethylstannylpropyl) (2) methyl‐malonates.Treated with urea under the usual conditions, (1) and (2) yield organostannyl barbituric acids.
