ADDUCT-ALDEHYDE AND ITS USE FOR THE PREPARATION OF A VITAMIN-D COMPOUND

An adduct-aldehyde of formula (I) is new. In (I), R = H or opt. etherified or esterified OH; R1 = opt. etherified or esterified OH; Z = sulphonyl or a gp. of formula A and B independently = 1-4C alkoxy; or A and B together form phenylimino or o-phenylene.
