METHODS OF SELECTIVELY FORMING SUBSTITUTED PYRAZINES

The present invention provides methods of selectively forming substituted pyrazines. Methods of the present invention can include receiving a reaction solution including at least one carbon source andat least one nitrogen source, and heating the reaction solution to a reaction temperature and holding the reaction solution at the reaction temperature for a time sufficient to produce a reaction product comprising at least one substituted pyrazine. The carbon source can be selected from the group consisting of hydroxy ketone(s), sugar(s) treated with at least one buffer, and combinations thereof. Tobacco products incorporating substituted pyrazines are also provided. 提供了选择性形成取代的吡嗪的方法。本发明的方法可以包括接收包含至少一种碳源和至少一种氮源的反应溶液，将该反应溶液加热至反应温度，并将该反应溶液在反应温度下保持足以生成包含至少一种取代的吡嗪的反应产物的时间。所述碳源可以选自羟基酮、用至少一种缓冲剂处理的糖以及它们的组合。还提供了掺有取代的吡嗪的烟草产品。
