Abstract
The synthesis of a series of bifunctional siloxymethyl isocyanate monomers, required for the solid phase synthesis of structurally defined polyurethane oligomers and copolymers is described. Thus, the MDI mimics 2, 3 were synthesised via a desymmetrisation sequence from di-p-tolylmethanone and the tert-butyld iphenylsiloxymethylaryl isocyanates 19, 22 and tert-butyldiphenylsiloxyethoxyethyl isocyanate 25, an aliphatic variant, which were all synthesised from commercially available amino alcohols.
