Alcohols Q 0230Allylation of Aldehydes and Imines: Promoted by Reuseable Polymer-Supported Sulfonamide of N-Glycine. -The reaction affords the products in high yields and most of the -SnBu3 residue is recovered as Bu3SnCl. The polymeric promoter can be reused at least five times without loss of activity. The method is further used for the preparation of bioactive natural products L-733,060 (XVII) and CP-99,994 (XVIII).
