摘要

The following process is new (R1 = hydroxyphenyl, an aliphatic, cycloalkphatic or araliphatic gp. or the gp. R2 = aryl or, when R1 = (A), an aliphatic, cycloaliphatic or araliphatic gp.; R3 and R4 are each H, aliphatic gp. or alkoxy. R5 = H or, when R1 is not hydroxyphenyl or (A), an aliphatic, cycloaliphatic or araliphatic gp.; R6 = same or different H, aliphatic, araliphatic or aromatic gps.).
