Abstract

Triphenylphosphine tagged with a short poly (ethyleneglycol)-ω-monomethyl ether chain (light MPEG, 10− 16 ethylenoxy units, MTPP-G2) and an MPEG-tagged version of diethyl azodicarboxylate (MDEAD) 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 ...
