Abstract

New analogues of castasterone, (20<i>R</i>)-2α,3α-dihydroxy-7a-homo-5α-cholestan-7-one (<strong>12</strong>) and (20<i>R</i>)-3α,4α-dihydroxy-7a-homo-5α-cholestan-7-one (<strong>14</strong>), and brassinolide, (20<i>R</i>)-2α,3α-dihydroxy-7a,7b-dihomo-7a-oxa-5α-cholestan-7-one (<strong>15</strong>), (20<i>R</i>)-3α,4α-dihydroxy-7a,7b-dihomo-7a-oxa-5α-cholestan-7-one (<strong>16</strong>) and (20<i>R</i>)-7-oxa-7a-homo-5α-cholestan-2α,3α-diol (<strong>24</strong>), were synthesized and their biological and spectral properties studied. <p>
