N-acyl- and N-alkoxycarbonylaminophthalimides are prepared using a convenient reaction and are efficiently used as acid partners in Mitsunobu reaction. This reaction allows them to be alkylated by primary, secondary or benzyl groups. Comparison of the reactivities and pK(a) values of these N-substituted aminophthalimides suggest that the success of the Mitsunobu reaction in this case seems to be governed

Application of a capture-ROMP-release strategy for the chromatography-free purification of Mitsunobu reaction products is described. Norbornenyl-tagged reagents are utilized for standard solution phase Mitsunobu chemistry. Post-reaction phase-switching is accomplished via in situ ring-opening metathesis polymerization (ROMP) followed by precipitation of the polymer with methanol. Release of the product from the polymer affords amines and alkyl hydrazine derivatives with good yields and purities. (C) 2003 Elsevier Ltd. All rights reserved.
