Both the enantiomers of stellettadine A (1), a bisguanidinium alkaloid isolated from a marine sponge Stelletta sp., are synthesized by starting from (S)- and (R)-citronellal (2). The absolute configuration of naturally occurring 1 is established as R.
stellettadine A (1) 是一种从海绵 Stelletta sp. 中分离出来的双胍生物碱,其两种对映体均以 (S)- 和 (R)-香茅醛 (2) 为原料合成。天然存在的 1 的绝对构型被确定为 R。
