Synthesis and Akt inhibitory properties of a 1d-3,4-dideoxyphosphatidylinositol ether lipid
摘要:
1D-3,4-Dideoxyphosphatidylinositol ether lipid 2, a PI analog, was synthesized through a sequence of protection/deprotection protocols and two Barton deoxygenation reactions, starting from L-(-)-quebrachitol. DDPIEL is 18-fold more potent than its monodeoxy counterpart DPIEL in the inhibition of P13-K. (C) 2000 Published by Elsevier Science Ltd.

inositols by blocking all but one hydroxyl group, converting the free hydroxyl group into its S -methyl dithiocarbonate, and treating it with tributylstannane. Suitable blocking-groups are methyl, benzyl, and methylthiomethyl ethers, and acetals. One cyclohexanepentol was prepared by the reductive deamination of an aminodeoxyinositol.
Photooxygenation of 1,4-cyclohexadiene 3 followed by reduction with LiAlH4 or thiourea gave (25/1)-cyclohex-3-ene-triol 7a. trans-Hydroxylation of triol 7a with three different methods afforded both of proto-quercitol la and vibo-quercitol 2a.
