โœฆ Synopsis

The reaction of nitro olefins reacted with (E)-(2-hydroxyphenyl)-1-nitroethylene in the presence of DABCO generates 3-nitrochroman with a high stereoselectivity. A possible reaction mechanism for the reaction and the transition states involved in producing the final product are proposed. The treatment of 3-nitrochromans with t-BuOK give alkenes.

An Easy and Efficient Synthesis of 3-Nitrochromans. -The reaction of nitro olefins (II) with (I) in the presence of DABCO generates 3-nitrochromans (III) with a high stereoselectivity. Interestingly, the sam nitrochroman is formed from both the (E)-nitroolefin and from the corresponding (Z)-isomer i
