Process for producing organic compounds using nitrites
A process produces an organic compound by allowing (A) a compound capable of generating a free radical to react with (B) at least one of esters and salts of nitrous acid in the presence of a nitrogen-containing cyclic compound constitutively having a skeleton represented by following Formula (i) in its ring: wherein X is an oxygen atom or an &#8212;OR group, and wherein R is a hydrogen atom or a hydroxyl-protecting group. Examples of the nitrogen-containing cyclic compound are cyclic imide compounds having a cyclic imide skeleton represented by following Formula (I): wherein n is 0 or 1; X is an oxygen atom or an &#8212;OR group, and wherein R is a hydrogen atom or a hydroxyl-protecting group.
