Synthesis of Enantiopure Homoallylic Alcohols

Synthesis and characterization of temperature‐sensitive block‐graft PNiPAAm‐b‐(PαN3CL‐g‐alkyne) copolymers by ring‐opening polymerization and click reaction

“…aClCL and PGA were prepared according to the reported method. 35,36 Organic solvents such as tetrahydrofuran (THF), methanol, chloroform, N,N-dimethylformamide (DMF) and n-hexane of high pressure liquid chromatography (HPLC) grade were purchased from Merck Chemical (Darmstad, Germany). Ultrapure water was prepared through purification with a Milli-Q Plus (Waters, Milford, MA).…”

C–O cleavage via InIII alkoxide intermediates: In situ 13C NMR analysis of the mechanism of an enantioselective in-mediated cyclopropanation reaction

“…The configurations of (R)-3b and (S)-3b were assigned by convergent synthesis involving alcohols (S)-12 and (R)-15, Scheme 4. The diastereoselective allylation procedure of Tietze [18] employing pseudoephedrine-derived reagent 13, was used to prepare (R)-15, via intermediate 14, for which the relative configurations have been unambiguously established by X-ray crystallography. [18] Resolution of (±)-3b and assignment of configurations by convergent synthesis.…”

A Simple Procedure for Connecting Two Carbohydrate Moieties by Click Chemistry Techniques

“…This compound was obtained by the procedure described in ref. [22] . The pure α anomer was separated from the α/β mixture by flash chromatography (dichloromethane/EtOAc, 98:2, 20 % yield).…”

“…This compound was obtained by the procedure described in ref. [22] The pure β product was isolated by flash chromatography (cyclohexane/EtOAc, 2:3 to 1:1, 43 % yield). [ 13 13…”
