An aminoalcohollibrary was constructed by parallelsynthesis based on Mannich-typethree-componentreactions of aldehydes, amines, and polymersupported silyl enol ethers, followed by reductive cleavage from the supports. “FieldSynthesis”, which provides an efficient method for the construction of libraries, is introduced.

A new linker resin for solid-phaseorganicsynthesis under Lewis acidic conditions has been developed. The resin, 5-(4′-chloromethylphenyl)pentylpolystyrene resin (CMPP resin), has no oxygen or nitrogen atoms in its spacer moiety. Imino aldol reactions of polymer-supported silyl enol ethers using the new resin with imines were demonstrated in the presence of a Lewis acid, and it was shown that the
