Abstract
The synthesis of (RS)-2-or (RS)-3-methoxy-2, 3-dihydro-5H-1, 4-benzodioxepins and (RS)-5- or (RS)-3-methoxy-2, 3, 5, 6-tetrahydro-8H-benzo-[1, 4, 7]-trioxecins has been developed. The mechanism of such a reaction via the boron trifluoride etherate-promoted transformation of 2-(methoxyethoxymethoxy) benzyloxyacetaldehyde dimethyl acetals or 2-( methoxyethoxymethoxymethyl) phenyloxyacetaldehyde dimethyl acetals has been ...
