1) cyclic acetal
环状缩醛
1.
The cyclic acetal exhibiting ambergris-like structure is prepared starting from β-pinene,the intermediates synthesized based on β-pinene are myrcene, myracaldehyde, 1,1-dimethyl-6(7)-methylal-octalin and 1,1-dimethyl-6,6(7,7)-dihydroxymethyl-octalin.
本研究以β-蒎烯为原料,经月桂烯、柑青醛、环柑青醛、1,1-二甲基-6,6(7,7)-二羟甲基八氢萘等中间体,合成了具有龙涎香型香料分子结构的环状缩醛,环状缩醛相对环柑青醛收率为66%。
