The present invention is a method for producing a 2-oxazoline analogue or a 1,3-oxazine analogue represented by the following general formula (3) by reacting a 1,2-aminoalcohol compound or a 1,2-aminothiol compound with an α,α-dihaloamine compound.
(In the formula, n represents 0 or 1, and R represents an oxygen atom or a sulfur atom. R1, R2 and R3 each represents an atom or a group shown in Group 1 to Group 3, and R° represents an atom or a group shown in Group 2 or Group 3. Two or more of R1, R2 and R3 may be bonded to each other to form a ring.
Group 1: a hydrogen atom, a halogen atom, a nitro group, a cyano group, a formyl group, a carboxyl group, a sulfonyl group, a sulfinoyl group or a sulfenyl group;
Group 2: an alkyl group, which may have an arbitrary substituent, an aryl group or an aralkyl group; and
Group 3: an alkyl-substituted, aryl-substituted or aralkyl-substituted oxy group, a carbonyl group, an oxycarbonyl group, a carbonyloxy group, a thio group, a sulfonyl group, a sulfinoyl group or a sulfenyl group)
本发明是通过使 1,2-氨基醇化合物或 1,2-氨基硫醇化合物与 α,α-二卤胺化合物反应,制得下通式(3)所代表的 2-噁唑啉类似物或 1,3-噁唑啉类似物的方法。
(式中,n 代表 0 或 1,R 代表氧原子或硫原子。R1、R2 和 R3 各代表第 1 组至第 3 组所示的原子或基团,R° 代表第 2 组或第 3 组所示的原子或基团。
第 1 组:氢原子、卤素原子、硝基、氰基、甲酰基、羧基、磺酰基、亚磺酰基或亚磺酰基;
第 2 组:可具有任意取代基的烷基、芳基或芳烷基;以及
第 3 组:烷基取代、芳基取代或烷基取代的氧基、羰基、氧羰基、碳酰氧基、硫代基团、磺酰基、亚磺酰基或亚磺酰基。)
