The present invention relates to an improved process to prepare cis-3-dihydrocarbylmethano-5-hydrocarbyidihydro-furan-2-ones. The present invention also relates to novel compositions of matter comprising enantiomerically pure cis-3-dihydrocarbylmethano-5-hydrocarbyldihydro-furan-2-ones, being the (3S,5S), (3R,5R), (3S,5R), or (3R,5S) optically pure isomers, and a new, more cost efficient process to prepare said optically pure isomers.
本发明涉及一种改进的工艺,用于制备顺式-3-双烷基甲基甲烷-5-羟基双烷基二氢呋喃-2-酮。本发明还涉及包含对映纯顺式-3-双烷基甲基甲烷-5-羟基二氢呋喃-2-酮的新型物质组合,即(3S,5S)、(3R,5R)、(3S,5R)或(3R,5S)光学纯异构体,并且提供了一种新的、更具成本效益的工艺用于制备这些光学纯异构体。
