The occurrence of musk fragrances (polycyclic musks in particular) in room air samples and house dust from 59 apartments and 74 kindergartens in Berlin in 2000 and 2001 was reported by Fromme et al. (2004a). Results are reviewed in Table 11.2. Musk compounds most often detected in the indoor air and dust were HHCB [1.3.4.6.7.8-hexahydro-4.6.6.7.8.8- hexamethylcyclopenta-(g) 2-benzopyrane, Galaxolide , Abbalide , Pearlide ], AHTN [7-acetyl-1.1.3.4.4.6-hexa-methyl-tetraline, Tonalide , Fixolide ] andmusk ketone (4-t-butyl-2.6-dimethyl-3.5-dinitroacetophenone). 

Table 1 Selected 1,3,4,6,7,8-hexahydro-2H-5-oxa-l-aza-phenanthren-6-yl derivatives and their corresponding physical properties. R- and S-enantiomers were prepared using either the (.R)- or (S )-[2-(f-butyl-(dimethyl-silanyloxy-methyl)-8-methyl-chroman-7-yl]-carbamic acid f-butyl ester in Step 1...

To trimethylsilylacetylene (20.4 mmol) dissolved in 80 ml THF at —5°C was added n-butyl lithium (20.4 mmol) followed by the dropwise addition of 3-isobutyl-9,10-dimethoxy-l,3,4,6,7,llb-hexahydro-2H-benzo[a]quinolizidin-2-one dissolved in 30ml THF. The mixture was stirred at -5 °C one hour, slowly warmed to 20 °C, stirred 2 hours, and then quenched with NH4CI solution. THF was removed, the aqueous component extracted 3 times with 100 ml EtOAc, washed with water, brine, and concentrated. The residue was dissolved in 30 ml methyl alcohol containing 5 ml 5 M KOH, heated to 65 °C 30 minutes, then cooled and quenched with NH4CI solution. The solution was concentrated, extracted 3 times with 50 ml EtOAc, washed, dried, and the product isolated in 53.7% yield as a slightly brown solid. Elemental analysis data supplied.
