摘要：

The development of a high-load, soluble oligomeric sulfonyl azide using ROM polymerization is reported. The utility in diazo transfer reactions with active methylene compounds is demonstrated using an efficient protocol, with most reactions showing completion in 30 min. The sulfonamide byproduct, being insoluble in the reaction solvent, can be completely removed by simple filtration through a silica gel SPE cartridge. (c) 2005 Elsevier Ltd. All rights reserved.
