Yield:-
Reaction Conditions:
with pyridinium chlorochromate;molecular sieve in dichloromethane;toluene
Steps:
R.1 Reference Example 1
Then, 2.8 g (0.025 mole) of the obtained (-)-(1S,2S,4R)-exo-norborneol was dissolved in 56 ml of methylene chloride, and 8.1 g (1.5 mole) of pyridinium chlorochromate (PCC) and 1 g of molecular sieve 4A were added thereto. The reaction was conducted at a temperature of 25° C. to 30° C. for 1 hour. Then, the reaction mixture was diluted with 56 ml of toluene, and the resultant was allowed to pass through a column of 28 g silica gel to remove insoluble materials. The elude was concentrated and dried to give crude (+)-norcamphor as a white crystal line powder.
