was washed three times with 25-mL portions of water, twice with 25-mL portions of 5% aqueous K2C03, and finally with saturated salt solution. The organic layer was dried over MgS04 and concentrated.l-Acetoxy-2-nitro-3,3,5,5-tetramethylcyclohexene was isolated by fractional crystallization from ether at low temperatures, and after recrystallization from ether 0.75 g of white crystals was obtained: mp 84-85 °C;
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
