Condensation of L- and D-3′-amino-2′,3′-dideoxynucleosides 2–5 with N-BOC-protected aminoacids 6 and 13 using dicyclohexylcarbodiimide and N-hydroxysuccinimide in DMF is reported to give the N-BOC-protected acylamino aminonucleosides 7–9 and 14 in 51–81% yield. After deprotection using trifluoroacetic acid the corresponding unprotected new analogues of puromucin 10–12 and 15 were obtained in 43–56%
据报道,在DMF中使用二环己基碳二亚胺和N-羟基琥珀酰亚胺使L-和D-3'-氨基-2',3'-二脱氧核苷2-5与N -BOC保护的氨基酸6和13缩合,得到N -BOC保护的酰氨aminonucleosides 7- 9和14中51-81%的产率。用三氟乙酸脱保护后,相应的未保护的新的嘌呤霉素10-12和15类似物以43-56%的产率获得。使用HIV(HTLV-III B染色)感染的MT-4细胞作为靶标系统,这些化合物未显示任何显着的抗病毒活性。
