Reduction of 5-alkyl-5-nitro-1,3-diheterocycloalkanes by sodium alcoholates

Zorin, V. V.,Kukovitskii, D. M.,Todres, Z. V.,Zlot-skii, S. S.,Rakhmankulov, D. L.

, p. 1635 - 1638 (2007/10/02)

In the reaction of 5-alkyl-5-nitro-1,3-diheterocycloalkanes containing oxygen and nitrogen as heteroatoms with sodium alcoholates in the corresponding alcohol 5-alkyl-1,3-diheterocycloalkanes, the corresponding aldehydes (or ketones), and diols are formed.A mechanism is proposed for the formation of the reaction products, including the stage of one-electron transfer from the alcoholate to the nitro group of the 5-alkyl-5-nitro-1,3-diheterocycloalkane.
