synthesis of (±)-anisomelic acid (34) has been achieved starting from aldehyde 7, the ozonolysis product of geranyl acetate. Two key steps ensured the stereoselectivity of the synthesis. The first entailed a highly anti-selective addition of the allyltitanium derived from carbamate 15 to aldehyde 5 affording the enol carbamate allylic alcohol 16. The second was a highly (Z)-selective Horner-Emmons cyclization
