Abstract

The utility of d-amino-n,@-ynones in the chirospecific synthesis of sphingosine is demonstrated. Thus, a protected L-serine isoxazolidide has been converted to sphingosine by two routes, both via a, P-ynones. The first route is very short and high yielding, merely involving two selective reductions after synthesis of the appropriate a, P-ynone. The second route involves alkylation of a 0-unsubstituted ynone and illustrates the synthetic versatility ...
