1,5-Cyclooctadiene was deprotonated under LICKOR conditions and reacted with Merrifield resin to afford an immobilized cyclooctadiene in high yield. This polymer is effective as a halogen scavenger, while hydroboration leads to a supported 9-BBN analogue. The latter exhibits similar regioselectivity

Diazo esters, arylboranes, and carbamoyl imines undergo a 3-component Mannich condensation reaction. Catalyzed by Cu(II) salts, the reaction affords the corresponding isocyanate Mannich product: one that can be easily trapped in situ by other nucleophiles. The Mannich condensation corresponds to

Solid-phase synthesis is a powerful tool for achieving high-throughput chemistry. This review discusses recent diverse examples from my group: the solid-phase synthesis of unsymmetrical guanidines, polymer-supported versions of cyclooctadiene and 9-BBN, a triflate-like linker, the synthesis of tetrahydro-beta-carbolines by the
