Process for producing optically active chroman derivative and intermediate |
| abstract |
A process for easily producing various optically activenchroman derivatives that are useful as pharmaceuticalnintermediates from inexpensive starting materials isnprovided. n Cyclic hemiacetal (1) obtained from dihydrocoumarinnthrough one step is asymmetrically reduced to produce annoptically active halohydrin derivative (3), and thenoptically active halohydrin derivative (3) is cyclized tonproduce an optically active chroman derivative (13): |
