In this period, we have developed the selective reduction by borohydride derivatives, the asymmetric aldol reaction and diastereoselective alkylation reaction employing a camphor-based chriral oxazinone auxiliary. Also, We have developed the various reaction using metal-catalyst. Lastly, we have carried out the total synthesis.
