Efficient Syntheses of 5-Aminoalkyl-1H-tetrazoles and of Polyamines Incorporating Tetrazole Rings
摘要:
Linear N-omega-tritylated omega-amino th iobenzylam ides and N-alpha,N-omega-ditritylated polyamino mono- or bisthioamides were efficiently converted to the corresponding tetrazole derivatives upon treatment with azidotrimethylsilane under Mitsunobu reaction conditions.
Aminolysis of N-Tritylamino Acid Benzotriazolyl Esters with Concentrated Aqueous Amines and its Applications in Synthesis.
摘要:
Aminolysis of (S)-N-tritylamino acid benzotriazolyl esters with concentrated aqueous amines produces high yields of the corresponding amides which can be readily detritylated with p-toluensulfonic acid or reduced with lithium aluminium hydride to provide chiral ethane-1;2-diamine derivatives.
