The present invention refers to 3,7-dimethyloct-6-en-1-yl methyl carbonate and its use as fragrance ingredient. The invention further refers to fragrance compositions and fragranced articles comprising it.
preparative synthesis, but additionally the catalytic mechanism was discussed and the clear impact of this rarely observed carbonate-derived acyl enzyme was shown. The presented protocol is characterized by atom efficiency, acyldonor sustainability, easy acyl group removal, mild reaction conditions, and biocatalyst recyclability, which significantly decreases the cost of the reported process.

Efficient and greenersynthesis of unsymmetricalorganiccarbonates is of great importance. In this work, two organotin-oxometalates, Bu2SnMoO4 and (Bu3Sn)2MoO4, were prepared and their catalytic performance for the transesterification of diethyl carbonate (DEC) with alcohols to synthesize unsymmetricalorganiccarbonates was studied. It was found that (Bu3Sn)2MoO4 was very active and selective for the transesterification
