A method and apparatus for hybrid multi-layer transmission includes receiving a multi-layer signal from a source device, wherein the multi-layer signal includes a plurality of sublayers. A quantity of the plurality of sublayers is decoded and partial information relating to the decoded sublayers is transmitted to a destination device.

Optical resolution of trans-tetrahydrofuran-2,5-dicarboxylic acid (13) was carried out via the (+)-2-(1-aminoethyl)naphthalene salt, and conversion of the (+) enantiomer 13 into (+)-2,5-dimethyltetrahydrofuran (17) of known configuration established its 2R,5R configuration.Condensation of (+)- and (-)-trans-ditosylates 15 and cis-ditosylate 20 with pyrocatechol afforded (-)-D2-trans,trans-8, (-)-C1-cis,trans-9, meso-C2h-trans,trans-10, and a mixture of meso-C2h-11 and meso-C2v-cis,cis crown ethers 12.Their selective transport of alkali metal cations is reported.
