  Asymmetric Synthesis of Isoquinoline Alkaloids: (R)- and (S)-2-Ethoxycarbonyl-1-Formyl-6, 7-Dimethoxy-1,2,3,4-Tetrahydroisoquinoline as Versatile Precursors

  摘要：

  AbstractA method is described for the preparation of (R)‐ and (S)‐2‐ethoxycarbonyl‐1‐formyl‐6,7‐dimethoxy‐1,2,3,4‐tetrahydroisoquinoline involving a Swerntype oxidation of (R)‐ and (S)‐2‐ethoxycarbonyl‐1‐hydroxymethyl‐6, 7‐dimethoxy‐1,2,3,4‐tetrahydroisoquinoline {(R)‐ and (S)‐2‐(ethoxycarbonyl)calycotomine}. The utility of these aldehydes in asymmetric synthesis of isoquinoline alkaloids has been demonstrated by their conversion into (S)‐ and (R)‐xylopinine, respectively; also, the (R)‐aldehyde has been employed for the synthesis of (8S,14S)‐coralydine.

  Continuous-flow enzymatic resolution strategy for the acylation of amino alcohols with a remote stereogenic centre: synthesis of calycotomine enantiomers

  摘要：

  Both enantiomers of calycotomine (R)-5 and (S)-5 were prepared through the CAL-B-catalysed asymmetric O-acylation of N-Boc-protected (6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolin-1-yl)methanol [(+/-)-3)]. The optimum conditions for the enzymatic resolution were determined under continuous-flow conditions, while the preparative-scale resolution of (+/-)-3 was performed as a batch reaction with high enantiselectivity (E>200). The resulting amino alcohol (S)-3 and amino ester (R)-4, obtained with high enantiomeric excess (ee = 99%), were transformed into the desired calycotomine (S)-5 and (R)-5 (ee = 99%). A systematic study was carried out in a continuous-flow system on the O-acylation of tetrahydroisoquinoline amino alcohol homologues (+/-)-1 to (+/-)-3 containing a remote stereogenic centre.
