scheme or table, p. 1440 - 1447 (2010/03/24)
The optically active hydroxyphenylselenides derived from the p-menthane, carane, and pinane systems have been obtained. Two methods of hydroxyphenylselenides synthesis have been compared. The first method is based on the reaction of alkenes with N-(phenylseleno)succinimide in the presence of water, and the second from epoxides as a result of the reaction with sodium benzeneselenolate. The influence of the substrate structures on the composition of the obtained products has been demonstrated.

(Chemical Equation Presented) Asymmetric Baeyer-Villiger reaction of symmetrical cyclobutanones 1a-j with urea-hydrogen peroxide (UHP) can be catalyzed by a complex of Pd(II) and the new terpene-derived P,N-ligand 7. The resulting lactones 2a-j were obtained in high yields and with good enantioselectivity (≤81% ee).
The enantioselective syntheses of bisabolane sesquiterpenes Lepistirone and Cheimonophyllon E

, p. 2397 - 2398 (2007/10/03)
The synthetic approach to the bisabolane sesquiterpenes Lepistirone 1 and Cheimonophyllon E 2 involves the transformation of (+)-2-carene (5) into the p-menthane furans 8 and 11. Regio- and stereoselective alkylation, and standard reactions complete the e
