Abstract

(1S, 2S, 3R, 5S)-and (1S, 2S, 3R, 5S)-3-Amino-2-hydroxypinane (1 and 2) were prepared from the corresponding α-pinene in optically pure form. They and their derivatives reacted with various organoborane compounds. A variety of chiral oxazaborolidines 3a-e and 4 were obtained in high yield
