Synthetic dehydroepiandrosterone (DHEA) phosphatide 1c, (R = C15H31), was prepared by three methods. The most efficient of these involved the coupling of the commercially available DHEA 1a and commercially available phosphatidic acid 2, via mesitylene sulfonyl chloride and pyridine. Alternatively, DHEA-3-phosphate 1b was coupled with dipalmitoyl glycerol 3 in the same way. The third synthesis gave 1c by coupling DHEA with the cyclic phosphotriester 4 followed by deblocking.

UI	MeSH Term	Description	Entries
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

D003687	Dehydroepiandrosterone	A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.
