摘要:
An intermediate in the synthesis of indinavir is prepared by iodohydroxylating an allyl acetonide by hypoiodous acid generated in situ from sodium hypochlorite and sodium iodide. ##STR1##
摘要:
Intermediates of structural formula ##STR1## can be made by reacting a primary or secondary amine with glycosidol or an activated derivative thereof. The process and intermediates are useful for synthesizing HIV protease inhibitor compounds.
摘要:
A process for making a clinically efficacious HIV protease inhibitor Compound J eliminates one step in its synthesis, by an improved, alternative synthesis of the 2(S)-4-picolyl-2-piperazine-t-butyl-carboxamide intermediate.
摘要:
The present invention is concerned with a process for preparing compounds of the general formula (I). These compounds can preferably be used to prepare bioactive agents. The reaction of the invention starts from the corresponding hydroxy compounds which are oxidized, with Ru catalysis, in a one-phase aqueous system.
摘要:
5-formyl-2-furylboronic acid is produced by a) adding a base to a composition containing a boric acid ester and 2-furaldehyde, thereby obtaining a reaction mixture and protecting the formyl group of said 2-furaldehyde with a protective group, b) working-up of the reaction mixture in an acidic medium, and c) isolating of the 5-formyl-2-furylboronic acid.
摘要:
The present invention is concerned with novel processes for the preparation of (2R-cis)-2-[[1-[3.5-bis(trifluoromethyl)phenyl]ethenyl]oxy]-3-(4-fluorophenyl)-4-(phenylmethyl) mopholine. This compound is useful as an intermediate in the synthesis of compounds which possess pharmacological activity.
