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.
A general methodology for the total synthesis of N-alkyl- and acylpolyamine derivatives is described which is based on the coupling of suitable N-tritylamino acids with amines followed by lithium aluminium hydride reduction of the thus obtained amides.
