Understanding the mechanism of procedure-controlled enantioselectivity switch in cinchona alkaloid thiourea catalyzed [3+2] cycloaddition: H-bonds controlled enantioselectivity

Density functional theory has been applied to the novel procedure-controlled enantioselectivity switch in the synthesis of chiral 2-oxazolidinone (3) through [3+2] cycloaddition between gamma-hydroxy-alpha,beta-unsaturated carbonyl compound (1) and isocyanate (2) catalyzed by a cinchona-alkaloid based aminothiourea catalyst. The study shows that three stages are involved in the whole process. In stage one, for Procedure A, 1 reacts with 2 to give carbamate intermediate. Then catalyst 4 is added. For Procedure B, catalyst 4 first activates 2 via quinuclidine N attacking isocyanate C. Then 1 is involved. In stage two, hydrogen is transferred from carbamate N to Ts O atom which is different from the quinuclidine N protonation mechanism. The last step is ring closure in which carbamate N attacks C atom of CC bond. From free energy profiles, the enantioselectivities of the reaction are determined by stage two. Further analysis shows that H-bond is the key in the procedure-controlled enantioselectivity switch. Different H-bonds (NAHA?OAC and NBHB?OAC in Procedure A vs NAHA?OAC and NBHB?OBS in Procedure B) lead to different relationships between thiourea and carbamate planes (vertical or parallel). In Procedure A, CC listing above carbamate plane is the favorable pathway to give R-3. However, in Procedure B, CC listing behind carbamate plane is more favorable to generate S-3.

Synthesis and absolute configuration of acanthodendrilline, a new cytotoxic bromotyrosine alkaloid from the Thai marine sponge acanthodendrilla sp.

Acanthodendrilline (1), a new bromotyrosine alkaloid, was isolated from the Thai marine sponge Acanthodendrilla sp. The structure of 1 was fully characterized by spectroscopic analysis, in agreement with the synthesized compound used to resolve the single chiral center at C-11. Total synthesis of the enantiomers of 1 allowed for the comparison of specific rotation values and hence the determination of the absolute configuration as 11-S. Cytotoxicity evaluation revealed that (S)-1 exhibited approximately three-fold more potent cytotoxicity against the human non-small cell lung cancer H292 cell line than (R)-1.
