Cyclophostin, a structurally unique and potent naturally occurring acetyl cholinesterase (AChE) Inhibitor, and its unnatural diastereomer were prepared in 6 steps and 15% overall yield from hydroxymethyl butyrolactone. The unnatural diastereomer of cyclophostin was converted into cyclipostin P, a potent naturally occurring hormone sensitive lipase (HSL) inhibitor, using a one pot dealkylation-alkylation process. The inhibition [IC50] of human AChE by cyclophostin and its diastereomer are reported, as well as constituent binding (K-1) and reactivity (k(2)) constants.
