    • A process comprising reacting a 2-methyloxazoline with a 3-methyl-2-buten-1-yl derivative of the formula ##STR1## in which X is halide, sulphonate or phosphate thereby to produce a 2-methyl-3-(3-methyl-2-butenyl)-2-oxazolinium salt of the formula ##STR2## reacting the oxazolinium salt with an alcoholate of the formulaR.sup.5 --O--M (V)in which M is one equivalent of an alkali metal or alkaline earth metal cation, to produce an oxazolidine of the formula ##STR3## pyrolyzing the oxazolidine to produce a 2-methyl-3-(3-methyl-2-butenyl)-oxazolindine of the formula ##STR4## and heating the 2-methylene-3-(3-methyl-2-butenyl)-oxazolidine to produce a 2-(2,2-dimethyl-3-buten-1-yl)-2-oxazoline.
    • 一种方法,包括使2-甲基恶唑啉与式(VII)的3-甲基-2-丁烯-1-基衍生物反应,其中X为卤化物,磺酸盐或磷酸盐,从而产生2-甲基-3- (Ⅳ)的(3-甲基-2-丁烯基)-2-恶唑啉盐(Ⅳ)使恶唑啉盐与式为R5-OM(Ⅴ)的醇化物反应,其中M为1当量的碱金属或 碱土金属阳离子,以产生式(III)的恶唑烷,式(III)热解恶唑烷以产生式“IMAGE”的2-甲基-3-(3-甲基-2-丁烯基) - 恶唑啉并加热 2-亚甲基-3-(3-甲基-2-丁烯基) - 恶唑烷,得到2-(2,2-二甲基-3-丁烯-1-基)-2-恶唑啉。
