title: Efficient synthesis of novel 1alpha-amino and 3beta-amino analogues of 1alpha,25-dihydroxyvitamin d(3).
abstract: Convenient synthetic routes to 1alpha-amino-25-hydroxyvitamin D(3) (3) and 3beta-amino-3-deoxy-1alpha,25-dihydroxyvitamin D(3) (4), novel analogues of vitamin D(3) bearing an amino group at the C-1 or C-3 position, have been developed starting from (S)-(+)-carvone. Construction of the A-ring fragments was accomplished by selective enzymatic hydrolysis of a diester intermediate and introduction of the amino group under Mitsunobu conditions.
