Abstract

Pyrrolophenylalkanolamines of the formula ##STR1## R.sup.1 and R.sup.2 represent hydrogen or various radicals, R.sup.3 represents hydrogen, acyl or trialkylsilyl, PA1 R.sup.4 represents hydrogen or alkyl, PA1 R.sup.5 represents hydrogen, or, together with R.sup.3, represents ##STR2## wherein R.sup.7 represents hydrogen or alkyl, and PA1 R.sup.6 represents branched or cyfclic alkyl, which is optionally substituted, and salts thereof promote the yield of animals. Many new intermediates are also shown.
