Abstract
PURPOSE: Titled compound used to produce polyurethanes containing adamantane skelton is prepared from 1,3-admantanedicarboxylic acid by one step reaction in high efficiency and yield without the formation of by-product causing pollution.
CONSTITUTION: As shown in the reaction equation, the reaction between 1,3- adamantanedicarboxylic acid of formulaI, diphenylphosphorylazide of formula II, and a monoalcohol of formula III (R is alkyl, ary, preferably methyl, t-butyl) is conducted in the presence of a trialkylamine, preferably triethylamine, to prepare the objective N-adamantylcarbamater ester of formula IV (A is -NHCOOR, -COOH). Above compounds of formulaIand IV may be appropriately substituted with one or two alkyl groups on the 5-and/or 7-positions in the adamantane skelton.
