    • In this reaction, it should be noted that we can avoid matched-mismatched problems when R has stererogenic centers (Scheme 1), because asymmetric induction is carried out at the remote position where the effect of R group becomes negligible. In fact, synthesis of the diastereomer 23 was also achieved with Soai protocol simply employing (R)-DPMPM to furnish 23 with 93:7 diastereoselecctivity. Further transformation of 23 using similar procedures in Scheme 2 afforded the allyl carbamate 24 in good yield (Scheme 4).
