合成路线:The condensation of N-methyl-N-(1-naphthylmethyl)propargylamine (I) with 1-bromo-2-tert-butylacetylene (II) by means of Cu2Cl2 gives N-methyl-N-(1-naphthylmethyl)-6,6-dimethylhept-2,4-diynylamine (III),which is then reduced selectively with diisobutylaluminurn hydride in toluene.
合成路线:The condensation of N-(1-naphthylmethyl)methylamine (IV) with formaldehyde and 5,5-dimethylhexadiine (V) by means of Cu2Cl2 also gives (III),which is then reduced selectively with diisobutylaluminum hydride in toluene.
合成路线:By reductocondensation of amino (IV) with 6,6-dimethylhept-2-en-4-ynal (VI) by means of NaBH4 in methanol.
合成路线:The condensation of propenal (VII) with tert-butylacetylene (VIII) by means of butyllithium gives 6,6-dimethylhept-1-en-4-yn-3-ol (IX),which is rearranged with HBr to the allyl isomer 6,6-dimethylhept-2-en-4-yn-1-yl bromide (X).Finally,this compound is condensed with amine (IV) by means of Na2CO3 in DMF.

合成路线:1) The Grignard reaction of 1-bromonaphthalene (I) with Mg in THF and then with [14C]-labeled CO2 gives the corresponding 1-naphthoic acid (II),which by reaction with SO2Cl2 and then with methylamine yields [14C]-N-methyl-1-naphthalenecarboxamide (III).The reduction of (III) with LiAlH4 in refluxing THF affords the corresponding amine (IV).Finally,this compound is condensed with 1-bromo-6,6-dimethylhept-2-en-4-yne (V) by means of Na2CO3 in DMF,and treated with ethanolic HCl.
合成路线:2) By condensation of (E)-N-methyl-N-(1-naphthylmethyl)-N-(pent-2-en-4-ynyl)amine (I) with [14C]-tert-butyl-chloride (II) by means of butyllithium and diethylaluminum chloride in hexane-dichloromethane.

合成路线:The rearrangement of 6,6-dimethylhept-1-en-4-yn-3-ol (I) (scheme 09027805a,intermediate (IX)) to 1-bromo-6,6-dimethylhept-2(E)-en-4-yne (scheme 09027805a,intermediate (X)) with HBr reports a stereoselectivity E/Z of only 3/1.An exhaustive study of this halogenation/rearrangement reaction has been performed.This reaction ((I) to chloride (II)) has been improved up to and E/Z ratio of 9/1 with reaction yields of 95%,the reaction conditions being BCl3 (1.25 molar ratio) in hexane,with a reaction temperature of 25 C.
