Reaction Conditions

Reaction Steps

383.0 g of 3,6,7-trimethyl-6-octen-1-in-3-ol and 0.3 g of Lindlar catalyst (5% Pd+3.5% Pb on CaCO3) are put in an autoclave and heated under nitrogen to a temperature of 45° C. Nitrogen is exchanged by hydrogen (H2) and the reaction mixture put at an absolute pressure of 2 bar. After the calculated amount of hydrogen has been consumed the reaction mixture is filtered and distilled (2 mbar, 115° C.) to obtain 3,6,7-trimethyl-6-octen-3-ol (=compound of formula (Ia)).
