Free radical methodology for carbohydrate to carbocycle transformations: An efficient synthesis of the tricyclic dihydrofuran portion of azadirachtin

Iodo lactone 6b, derived from D-galactal, undergoes tin hydride mediated transannular radical cyclization to give the tricyclic lactone 7, which is easily converted into an advanced precursor of the tricyclic dihydrofuran portion of the potent insect anti
