Indinavir – An Outline

The synthesis of the piperazine building block of indinavir using a extra convergent, efficient, and greener strategy that utilized asymmetric catalysis as an alternative of a resolution for the important thing intermediate 4.4.7, is shown in Scheme 12. An Ugi multicomponent response offered intermediate 4.4.16, which with out isolation was handled with triethylamine to bear elimination of HCl to afford 4.4.17. Cyclization of 4.4.17 to 4.4.18 was achieved in 60% yield by rigorously monitoring the reaction circumstances and the subsequent key asymmetric hydrogenation was accomplished with 7 mol% Rh-BINAP in methanol to provide 4.4.19 in quantitative yield and 97% ee.Forty Elimination of the formyl group with 35% aqueous hydrazine gave 4.4.7 in good yield risperdal without a doctor prescription racemization. Scheme 12. Synthesis of the piperazine portion (4.4.7) of indinavir (Crixivan). Reagents and circumstances: (a) Et3N; (b) t-BuOK; (c) 7 mol% Rh-BINAP, H2 (one hundred atm), kamagra oral jelly generic MeOH, 40 °C; (d) 35% aqueous hydrazine. The synthesis of the epoxide building block 4.4.23 is proven in Scheme 13.Forty one Intermediate 4.4.21 was obtained in two chemical steps from cis-1-amino-indanol (4.4.20)forty two after which alkylated with allyl bromide to afford 4.4.22 in a 96:Four ratio. Scheme 13. Greener indinavir method: Synthesis of intermediate 4.4.23. Reagents and circumstances: buy careprost + applicators online (a) Ref. 42; (b) LHMDS, allyl bromide, THF, −15 °C; (c) (i) NCS, NaI, IPAc, aqueous NaHCO3; (ii) NaOMe, THF. Scheme 14.
