In order to search for potent and environmental friendly insecticides with new modes of action, a series of pyranoside derivatives mimicking D-myo-inositol 1,4,5-trisphosphate (IP3) were designed and synthesized according to the bioisosteric approach. The biological assay indicated that most of the new compounds showed moderate to good insecticidal activities against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). Especially, compound 5g displayed 80% larvicidal activity against oriental armyworm at 50 mg/L. Meanwhile, 5a showed 100% and 70% larvicidal activities against diamondback moth at 50 and 25 mg/L, respectively. To further explore the mode of action, calcium imaging technique was applied to study the effects of 5a, 5g, and 5i on the intracellular calcium ion concentration ([Ca2+]i) in central neurons isolated from Spodoptera exigua. The results indicated that the tested compounds released stored calcium ions from endoplasmic reticulum.
The allyl group for protection in carbohydrate chemistry. XXXI conversion of allyl 2,6-di-o-benzyl-α-d-galactopyranoside into allyl 2,6-di-o-benzyl-α-d-glucopyranoside and 2,6-di-o-benzyl-d-glucopyranose

Allyl 2,6-di-O-benzyl-α-D-galactopyranoside was converted by tin-mediated alkylation into the 3-O-p-methoxybenzyl ether which gave the 4-0-mesyl derivative. Sodium benzoate in refluxing N,N-dimethylformamide converted the last compound into allyl 4-O-benz

A concise synthetic route from D-glucose to a chiral, biologically active, phosphorylated analogue of the highly potent Ca2+-mobilising agonist adenophostin A has been developed, involving a regioselective dibenzylation of allyl α-D-glucopyranoside and a one-pot Lemieux-type allyl oxidation with subsequent reduction and neighbouring deketalisation, to provide the key intermediate for phosphorylation.
