Acyclic alkanols

Note In acyclic alkanols, the OH-bearing carbon receives the number 1 only when it is located at the end of the stem chain.

Chain-Extending Syntheses of a-Phenylsulfenyl Ketones. A C-C connective, chain-extending synthesis of a-phenylsulfenyl ketones from aldehydes (eq 65) or acyclic ketones (eq 66) can be accomplished by a CuOTf-promoted activation of the a-[bis(phenylthio)methyl]alkanols generated by addition of lithium bis(phenylthio)methide. Preferential migration of hydride generates phenylsulfenylmethyl ketones...

Lewis and Hirsch studied four a-cycloalkoxyacetophenones, in which the ring is even farther away from the carbonyl and the y-hydrogen is tertiary.Table 58.3 lists the results, which consist of oxas-piro[3,n]alkanol and cycloalkanone formation, via normal cyclization and cleavage of the 1,4-biradicals. Simple isopropoxyacetophenone is included for the sake of comparison to acyclic compounds. As with other a-alkoxy ketones, overall quantum yields are quite high and cyclization yields are reasonable, except for the cyclopropyloxy ketone. Hydrogen abstraction rate constants are very high and decrease as expected as the rings get smaller.
