BORON TRIBROMIDE-METHYL SULFIDE COMPLEX Usage And Synthesis

Uses

Reactant for preparation of:

• Precursor of HIV protease inhibitor KNI 764 using cation-exchange resin mediated Mannich reaction

• Baylis-Hillman reactions

Uses

Boron tribromide dimethyl sulfide complex (BBr₃S(CH₃)₂) can be used as a reagent:

• To prepare demethylated products from aryl methyl ethers by deprotection of methyl groups.
• To hydrolyze 1,3-methylenedioxole ring compounds to 1,2-dihydroxy compounds.
• To prepare benzyl S,S′-diphenyl acetal by reacting with phenylacetic acid and thexylphenylthioborane.
• To synthesize Baylis?Hillman adducts and α-halomethyl enones by the reaction between aldehydes and 3-buten-2-one.
