NON-CYCLIC HINDERED KETONES AS PERFUMING INGREDIENT

The present invention relates to the use as perfuming ingredient of a compound of formula (I) wherein R represents a hydrogen atom or a methyl or ethyl group, and R1 represents (i) a (Me)(R2)C=C(R3) group, R2 representing a hydrogen atom or a methyl group and R3 representing a methyl or ethyl group, or (ii) a phenyl group optionally substituted by one or two methyl groups; as well as to the compositions or articles associated with said compound.

Reductive cleavage of 2-methyleneoxetanes with lithium and 4,4'-di-tert- butylbiphenyl

3,3-Dimethyl-2-mcthylene-4-phenyloxetane (5) undergoes reductive cleavage with lithium and 4,4'-di-tertbutylbiphenyl (DTBB) to give an intermediate dianion, which reacts regioselectively with aldehydes and ketones to give aldol adducts in modest yields. A
