4-alkoxy-1-alkene alkanal acetal

When heteroatom containing substrates react with peroxides, or other radical initiators, hydrogen atom transfer can occur, as in the transfer of hydrogen from an acetal to the radical, generating the alkane and the a-alkoxy radical, 133. The presence of the heteroatom a to the carbon bearing the radical center leads to enhanced stability. Such radicals add to alkenes, usually with anti-Markovnikov orientation, as in the radical...
