Resumen:
Biomass is a widely available raw material which has been recognized as an important source of fuels and chemical products. By far, carbohydrates are the major annually renewable biofeedstocks from which to develop viable organic chemicals that are to replace those derived from fossil sources. Among the plethora of natural molecules from the chiral pool, carbohydrates probably play an unsurpassed role as chiral auxiliaries in asymmetric synthesis regarding optical purity, number of stereogenic centers, availability and economics. Levoglucosenone is a versatile and readily available member of the carbohydrate derived chiral pool, which has been used as chiral synthon in the synthesis of a wide variety of compounds. As part of our program on the pyrolytic conversion of biomass into high value chemicals, we have been concerned with the synthetic application of levoglucosenone as a chiral building block in the development of new asymmetric inductors. Conventional pyrolysis of cellulose or cellulose-containing materials such as waste paper is typically used to generate levoglucosenone, but microwave irradiation of microcrystalline cellulose was recently found to be also effective.
