84. Selective Monoderivatization of Propane-1,3-diamine with Acid Chlorides: 'Hexahydropyrimidine Method' vs. Statistic Methods
The selective N-monoderivatization of propane-1,3-dmmine (5) with carbonyl and sulfonyl chlorides via 2-phenylhexahydropyrimidine (6) was compared with the direct statistic monoderivatization. It was found that, under optimized conditions, both methods ar
