Question

Spinosad is a relatively new insecticide that is made up of two complex organic compounds, Spinosyn A (right) and Spinosyn D. These compounds are produced by certain microbes that were first discovered in soil found at an abandoned rum factory. Assign chirality (Ror S) to the asymmetric carbons present in the circled areas of the structure of Spinosyn D below? (choose the correct listed set of chirality in order from A, B, C, and D labels on the structure) O Select one: a. S, S, SS b. S, R, S, R C. S, R, RS R, R, RR e. R, R, S,S f. RR,RS 9. S, RR,R

Answer 1

Date Saathi part which are that consider only find out ond 0 ② according to CIF Rule - give priority acc. to atomic no. check neighbouring atom antidockullie AS. clockwise so R but loulest group 7 at wedge so 4 1 convert to s R Bs H ewen change

atni clockwise so R. But lowest group P convert to s aree on wedge so clockulise so R Bel least group convert to s an wedge so R Ds --> S BS [option @ ssss DS
