摘要：

The chirogenic Diels/Alder reactions of the general pattern AB + D --> ABCD, (i): 2 + 3 --> rac-8a (major) + rac-9a (minor) (85%), (ii): 2 + 10a --> rac-11a (89%), and (iii): 2 + 10b --> rac-11b (90%), now have been accomplished in the presence of Lewis acid, (i): BF3.OEt2, (ii) or (iii): TiCl4. Case (iii) may be used as the initial move towards (+/-)-norgestrel (rac-14).
