Sato, Tsuneo,Wakahara, Yoshiyuki,Otera, Junzo,Nozaki, Hitosi
, p. 9773 - 9782 (2007/10/02)
Dibutyltin bis(triflate) is a mild Lewis acid which catalyzes clean Michael addition of enol silyl ethers.The new catalyst allows to employ various labile acceptors such as methyl vinyl ketone and 2-cyclopentenone which do not undergo smooth reaction with
Organotin triflates as functional Lewis acids. A new entry to simple and efficient Robinson annulation
Sato, Tsuneo,Wakahara, Yoshiyuki,Otera, Junzo,Nozaki, Hitosi
, p. 1581 - 1584 (2007/10/02)
An efficient Robinson annulation has been established through the Michael addition of enol silyl ethers to α-enones catalyzed by dibutyltinbis(triflate) followed by the MeONa-mediated intramolecular aldol condensation of the adducts.
Structure-odour relationships of some new synthetic sandalwood aroma chemicals. Synthesis and olfactive properties in a series of bicyclodecan-3-ols
Witteveen, Jan G.,Weerdt, Anton J. A. van der
, p. 29 - 34 (2007/10/02)
The relationship between chemical structure and sandalwood fragrance in a series of four isomers of 8-tert-butylbicyclodecan-3-ol (4a-d), the unsaturated analogue 5 and the methyl-substituted derivative 17 has been examined.The sandalwood fragrance
