To avoid the formation of by-products (V), the reaction is carried out as a three-component process with aldehydes (VI) or as four-component process with in situ formation of the olefins. — (KUMAR, S.; KAPOOR*, K.

To avoid the formation of by-products (V), the reaction is carried out as a three-component process with aldehydes (VI) or as four-component process with in situ formation of the olefins. — (KUMAR, S.; KAPOOR*, K.
