4'-Oxa-a-santalene and 4'-oxa-a-santalol: an olfactory comparison with the analogous natural sesquiterpenes

Allyl type organometallic intermediates allow the prepn. of the 4'-oxa analogs I (R = H, OH, X = O) of a-santalene (I; R = H, X = CH2) and a-santalol (I; R = OH, X = CH2) in a very convenient, regio- and stereocontrolled manner from bromotricyclene (II). T ...

The Diels-Alder approach to musk odor type arenes

The readily accessible 2-halogeno-1-trimethylsilyloxy-1,3-butadienes, e.g. CH2:CRCR1:CHOSiMe3 (R = H, Me; R1 = F, Cl) react smoothly with MeO2CC.tplbond.CCO2Me to afford 4-halophthalic esters, e.g. I. I (R = H, R1 = Fl) was subsequently converted into the ...
