Synthesis of Arrays Using Low Molecular Weight MPEG-Assisted Mitsunobu Reaction
摘要:
Triphenylphosphine tagged with a short poly(ethyleneglycol)-omega-monomethyl ether chain (light MPEG, 10-16 ethylenoxy units, (TPP)-T-M-G2) and an MPEG-tagged version of diethyl azodicarboxylate ((M)DEAD) have been used to prepare a 20 member library of esters, ethers, and sulfonamides, with cLogP's in the range of 1.4-5.7 on a 0.1 mmol scale. Removal of MPEG-tagged side products was achieved by MPEG-assisted solid-phase extraction (MSPE) on prepacked silica columns to give the products in good yield and high purity.
