    The invention comprises compounds of the formula <;FORM:0785373/IV (a)/1>; wherein R is a -(CH2)6- or <;FORM:0785373/IV (a)/2>; group and R2 is hydrogen, alkyl, aryl or aralkyl. It comprises also a process for the preparation of compounds of the formula <;FORM:0785373/IV (a)/3>; wherein X is O, S, NH or NR3 (R3 is an alkyl, aryl or aralkyl group), by reacting a compound of the formula R1OC­C-R2, wherein R1 is an alkyl group, with a compound of the formula H2N-R-XH. The reaction is suitably carried out by allowing an alkoxyacetylene, such as an ethoxyacetylene compound, to react with an aminoalcohol, a diamine or a mercaptoamine. Examples describe the preparation according to the above process of (1) 2-methyl-oxazoline; (2) 2 : 4-dimethyl-oxazoline; (3) 2-methylimidazoline; (4) 2-methylbenzimidazole; (5) 2-methylthiazoline; (6) 2-methyl-1-dodecylimidazoline-2; (7) 2-propyl-imidazoline-2; (8) 2-benzylimidazoline-2; (9) 2-methyl- D 2-dihydro-oxazine - 1 : 3; (10) 2 - methyl - 3 : 4 : 5 : 6 - tetrahydropyrimidine; (11) 2-methyl-4 : 5-benzooxazine-1 : 3; (12) 2-methyl-5 : 6-dihydro-1 : 3-thiazine; (13) 2-(1-naphthylmethyl)-2-imidazoline; (14) 2-heptadecyl-2-imidazoline; (15) 2-methyl - 4 : 5 : 6 : 7 - tetrahydro - 1 : 3 - diazepine and (16) 2-methyl-4 : 5 : 6 : 7 : 8 : 9-hexahydro-1 : 3-oxazonine.

    这项发明包括以下公式的化合物:<;FORM:0785373/IV (a)/1>;其中R是一个-(CH2)6-或<;FORM:0785373/IV (a)/2>;基团,R2是氢、烷基、芳基或芳基烷基。它还包括一种制备以下公式的化合物的方法:<;FORM:0785373/IV (a)/3>;其中X是O、S、NH或NR3(R3是烷基、芳基或芳基烷基),通过将公式R1OC­C-R2的化合物(其中R1是烷基)与公式H2N-R-XH的化合物反应。反应通常通过允许烷氧基乙炔,如乙氧基乙炔化合物,与氨醇、二胺或巯胺反应来进行。示例描述了根据上述过程制备的化合物(1)2-甲基噁唑烷;(2)2 : 4-二甲基噁唑烷;(3)2-甲基咪唑烷;(4)2-甲基苯并咪唑;(5)2-甲基噻唑烷;(6)2-甲基-1-十二烷基咪唑-2;(7)2-丙基咪唑-2;(8)2-苄基咪唑-2;(9)2-甲基- D 2-二氢噁啉 - 1 : 3;(10)2-甲基-3 : 4 : 5 : 6-四氢嘧啶;(11)2-甲基-4 : 5-苯噁啉-1 : 3;(12)2-甲基-5 : 6-二氢-1 : 3-噻嗪;(13)2-(1-萘甲基)-2-咪唑烷;(14)2-庚十七烷基-2-咪唑烷;(15)2-甲基-4 : 5 : 6 : 7-四氢-1 : 3-二氮杂环己烷和(16)2-甲基-4 : 5 : 6 : 7 : 8 : 9-六氢-1 : 3-噁唑烷。

    Trifluoroacetylations of cyclic ketene-N,O/S-acetals exhibit a ring size effect. The five-membered rings 2,4,4-trimethyl-2-oxazoline, 2-methyl-2-oxazoline, and 2-methyl-2-thiazoline, each form cyclic ketene-N,O/S-acetal intermediates which then react with trifluoroacetic anhydride to give β-monotrifluoroacetylation products. Conversely, the six-membered ring 2-methyl-2-oxazine gives its β,β-bistrifluoroacetylation
