용도

A higher order cuprate reacted with trans-2,3-epoxybutane a high yield both counted on the epoxide (96%) and on the haloalkane (85%). Enolate derived from trans-2,3-Epoxybutan has chiral recognition.

참고

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, water, moisture.
