METHODS FOR PRODUCING OPTICALLY ACTIVE OXAZOLINE COMPOUND, OPTICALLY ACTIVE TRANSITION METAL COMPLEX AND ASYMMETRIC DIELS-ALDER REACTION PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a new optically active bisoxazoline compound. SOLUTION: The invention relates to the optically active bisoxazoline compound expressed by general formula (1). In the formula R1, R2and R3are each independently H, a halogen atom, an alkyl, a cycloalkyl, an aryl, an arylalkyl, an alkoxy, an aryloxy, an alkenyl or an arylalkyloxy, each R1, R2and R3is the same or different and optionally form a ring by coupling. X is OR4or NR5R6. R4is H, an alkyl, an alkenyl, an aryl or an arylalkyl, R5and R6are each independently H, an alkyl, an alkenyl, an aryl or an arylalkyl. Every R4, every R5and every R6are each the same or different. COPYRIGHT: (C)2005,JPO&NCIPI
