Racemic 2′-aminomethyl-5-benzyl-acyclouridine (AM-BAU, 5) and 2′-aminomethyl-5-benzyloxybenzyla-cyclouridine (AM-BBAU, 6) have been found to be very active inhibitors of uridine phosphorylase [1]. Their enantiomers were synthesized from chiral 2,2-dimethyl-1,3-dioxolane-4-methanol (7a,b). S-(—)-AM-BAU (5a) and S-(—)-AM-BBAU (6a) were prepared from the R-(—) isomer 7a, and R(+)-AM-BAU (5b) and R-(+)-AM-BBAU
已发现外消旋的2'-氨基甲基-5-苄基-acyclouridine(AM-BAU,5)和2'-氨基甲基-5-苄氧基苄基-a-cyclouridine(AM-BBAU,6)是尿苷磷酸化酶的非常有效的抑制剂[1] 。它们的对映异构体由手性2,2-二甲基-1,3-二氧戊环-4-甲醇(7a,b)合成。S -(-)-AM-BAU(5a)和S -(-)-AM-BBAU(6a)由R -(-)异构体7a,R(+)-AM-BAU(5b)和来自S -(+)异构体7b的R -(+)-AM-BBAU(6b)。还确定了从S -(+)异构体7b到S -(-)-AM-BBAU(6a)的不同途径。
