ABSTRACT:
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, R2and R3each represents an atom or a group shown in Group 1 to Group 3, and R0represents an atom or a group shown in Group 2 or Group 3. Two or more of R1, R2and R3may 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; andGroup 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)
