(1S,2S,5R,6S )-6-(3,4-Methylenedioxyphenyl)-3,7-dioxabicyclo[3.3.0]octan-1,2-diol ((+)-1-hydroxysamin 1) was synthesized, starting from olefin 8. Stereoselective α-hydroxylation was achieved after converting 8 to aldehyde 13. Resulting unstable α-hydroxy aldehyde 14 was then transformed to (+)-1-hydroxysamin (1). This is a new efficient synthetic route to 1,2-oxygenated 6-arylfurofuran lignans.
(1S,2S,5R,6S )-6-(3,4-亚甲基二氧苯基)-3,7-二氧杂双环[3.3.0]辛烷-1,2-二醇((+)-1-羟基氨基1)是从烯烃8合成的。在将8转化为醛13后,实现了立体选择性α-羟基化。然后将所得的不稳定的α-羟基醛14转化为(+)-1-羟基氨基(1)。这是合成1,2
