Structurally simplified analogues of the daphnane diterpene resiniferatoxin (RTX) 1, possessing the unusual 2,9,10-trioxatricyclo3,8>decane system have been synthesised stereoselectively from cyclohexa-1,3-diene: functionalisation of th
Stereo- and Regioselective Palladium-Catalyzed 1,4-Dialkoxylation of Conjugated Dienes

A mild method for stereo- and regioselective 1,4-dialkoxylation of conjugated dienes was developed.The reaction is catalysed by palladium(II), and p-benzoquinone is used as the oxidant.It was found that the reaction rate depended on the presence of catalytic amounts of a strong acid.The role of the acid is probably 2-fold: (i) to create a cationic (?-allyl)palladium intermediate and (ii) to protonate the oxygen in the coordinated benzoquinone in the (?-allyl)palladium(benzoquinone) intermediate.

A facile procedure to synthesize cyclitols from cyclohexene was examined. 1-O-Benzylcyclohex-2-enol (1-benzyloxycyclohexene-2) (I) was prepared from cyclohexene by bromination and successive treatment with sodium benzyloxide.Compound I was converted, by using the same procedure, into DL-trans-1,2-di-O-benzylcyclohex-3-enediol (IIIa), DL-trans- and meso-cis-1,4-di-O-benzylcyclohex-2-enediols (IIIb and IIIc).The main product (IIIa) was converted into dihydroconduritols (IXc and Xc) via the corresponding di-O-benzylcyclohexanetetrols.
