<p>A pinene derivative represented by the general formula (I) or a salt thereof; and a process for producing the derivative or salt or a process for producing from the derivative or salt an optionally active 2-(t-butoxycarbonyl)amino-3-hydroxypropanoic acid derivative represented by the general formula (V) (in the formulae, R1 represents alkyl and R2 represents alkyl, alkenyl, alkynyl, a cyclic group, etc.). The 2-(t-butoxycarbonyl)amino-3-hydroxypropanoic acid derivative, which is useful as an important intermediate for medicines, can be efficiently synthesized from the novel intermediate represented by the general formula (I).</p> |
