Rrans-Cyclodecene

In an interesting contrast to the observed optical lability of rrans-cyclodecene, successful resolution (47) has been recently reported for 1,2-dimethyl-/rans-cyclodecene (22) and the higher homolog, 1,2-dimethyl-lrans-cycloundecene. 

Although OSO4 is thought of as a specific oxidant for cis alkenes there are a few examples of hydroxylation of trans alkenes, e.g. cis- and rrans-cyclodecene can be hydroxylated to the respective cis and irons diols. The 0s04-alkene-pyridine reaction can be made catalytic by the use of suitable secondary oxidants such as H2O2, CIOs", Bu OOH, iV-morpholine A-oxide, 104 , O2 and CIO"...
