pubmed-article:4641422 | pubmed:abstractText | Fatty acyl esters of N-hydroxysuccinimide have been used to directly N-acylate sphingenine or sphinganine, forming the corresponding ceramides. The reaction proceeds in excellent yield (84-96%) from small amounts of starting material (10-20 mg). The product ceramides are pure after one recrystallization. | lld:pubmed |
