Haloketal cyclization. The ketal nitrile (1) is cyclized to the cyclohexanone deriva live (2) by treatment with 1 -3 eq. of potassium hexamethyld isilazanc in benzene... [Pg.407]

The haloketal cyclization is most useful for synthesis of polycyclic systems. Thus (5) is converted into a < b-9-cyano-2-decalone (6), and (7) is converted into (8). The hydrin-dane (10) was prepared from (9). [Pg.408]
