clo[3.2.2]non-6-ene (13) which upon reductive NO ring cleavage, hydrogenation, oxidation and deprotection yielded the 3-hydroxy analogue 8-methyl-8-azabicyclo[3.2.1]octane-1,3-diol () of the tropane alkaloid physoperuvine.
3-叔丁基二甲基甲硅烷氧基-8-甲基-8-氮杂双环[3.2.1]辛-6-烯N-氧化物(11)和(12)在丁腈中的热解得到3-叔丁基二甲基甲硅烷氧基-9-甲基-8- oxa-9-氮杂双环[3.2.2]非6-烯(13),其通过还原N = O环裂解,氢化,氧化和脱保护得到3-羟基类似物8-甲基-8-氮杂双环[3.2.1]烷烃生物碱的辛烷-1,3-二醇()。
