1.6- Dioxaspiro decanes

Enantiomers of 7-methyl-1,6-dioxaspiro [4.5] decane 27 Decan-4-olide (Z,Z)-Octadeca-9,12-dienoic acid... [Pg.281]

In the final stages of the total synthesis of okadaic acid by C.J. Forsyth et al., the central 1,6-dioxaspiro[4,5]decane ring system was introduced by the enantioselective reduction of the Cl6 carbonyl group using (S)-CBS/BH3, followed by acid-catalyzed spiroketalization. ... [Pg.101]

We have discussed above the conformational profile of l,7-dioxaspiro[5.5]un-decane skeleton. There are examples of 1,6-dioxaspiro[4.5]decane skeleton as well, a skeleton that has been encountered in products of natural origin including the ionophores. Cottier et al. [25] have prepared several derivatives of 1,6-dioxaspiro [4.5]decane and shown that 175 exits as the conformer 175a in preference to 175b. These authors have also reported that the compound 176 exists in the conformation as shown, each ring oxygen having an electron pair orbital antiperiplanar to a polar... [Pg.34]
