Recyclization reactions of 8,10-dibromocamphor with Grignard and organolithium compounds

“…Camphor is known as the naturally available starting material in a number of syntheses of more complex compounds from the middle of the XIX century. Nowadays many syntheses of steroids [1][2][3], terpenoids [4][5][6][7][8][9][10][11][12], vitamins [13][14][15] and other natural products [16][17][18][19] that involve camphor or its derivatives are described in the literature.…”
