ABSTRACT:
Described are perfume and fragrance compositions and perfumed articles including soaps, detergents, powders as well as colognes containing 2,2,3-trimethyl-3-cyclopenten-1-ylalkenyl and alkylidene secondary alkanols, alkanones, cycloalkanols and cycloalkanones having the generic structure: ##STR1## wherein one of the lines +++++ is a carbon-carbon double bond and the other of the lines +++++ is a carbon-carbon single bond; wherein X is carbinol having the structure: ##STR2## or carbonyl having the structure ##STR3## wherein A' is hydrogen, CH.sub.3, C.sub.2 H.sub.5 or --CH.sub.2 --; wherein B' is hydrogen, CH.sub.3, C.sub.2 H.sub.5 or --CH.sub.2 --; where n is 0, 1 or 2; wherein each of the dashed lines are the same and each represents a carbon-carbon single bond or no bond; wherein A' and B' are both --CH.sub.2 -- when n is 1 or 2 and the dashed line is a carbon-carbon single bond or A' is hydrogen and B' is C.sub.2 H.sub.5 or CH.sub.3 or both A' and B' are each CH.sub.3 or A' is C.sub.2 H.sub.5 and B' is CH.sub.3 when n is 0 and the dashed line represents no bond, which imparts thereto rich, musky, cedar woody, sandalwood, sweet, floral, ionone-like, soft-fruity (apricot), green and earthy aromas with resinous topnotes and nutty oily nuances. Also described is a process for preparing such compounds according to the reaction schemes: ##STR4## wherein the lines +++++ A', B', the dashed lines and n are as defined above wherein M is alkaline metal.
