Abstract (en)

[origin: DE102006007883A1] Preparation of a menthylamide compound (I) comprises reacting a menthylhalide compound (II) with magnesium or lithium and optionally elementary iodine or an alkylhalogenide, and subsequently either with an isocyanate compound (III) or with a heterocyclic compound (IV) or with a carbamoylchloride compound (V). Preparation of a menthylamide compound of formula (I) comprises reacting a menthylhalide compound of formula (II) with magnesium or lithium and optionally elementary iodine or an alkylhalogenide, and subsequently either with an isocyanate compound (III) of formula (O=C=N-R 1>), or with a heterocyclic compound of formula (IV) or with a carbamoylchloride compound (V) of formula (Cl-CO-N(R 1>)(R 2>)). Either R 1>1-30C alkyl, 2-20C alkenyl, 2-20C alkynyl, 3-20C cycloalkyl, 3-20C cycloalkenyl, 3-20C cycloalkynyl, 1-20C hydroxyalkyl, 3-20C acyloxyalkyl, 1-20C alkoxy, 2-20C alkoxyalkyl, 2-20C alkylthioalkyl, 2-20C aminoalkyl, 3-20C acylaminoalkyl, 2-20C carboxyalkyl, -C nH 2nC(=O)R 4>or -C nH 2nCOOR 4>, where -C nH 2nis alkylene; and R 2>R 1>, H or -X-OH; or R 1>R 2>alkylene chain (optionally interrupted by one or more heteroatom); or NR 1>R 2>10 membered ring; R 3>H, 1-30C alkyl or 6-24C arylalkyl, where the methyl- and the isopropyl residue are present at the carbon atoms of the cyclohexyl ring and both the residues are present at the same carbon atom; Hal : chloro, bromo or iodo; R 4>H, 1-10C alkyl, 1-8C hydroxyalkyl, 1-8C alkoxyalkyl or 1-8C acyloxyalkyl; X : 1-20C alkylene group (optionally interrupted by one or more heteroatom); and n : 1-10.
