A naturally occuring antibiotic called mycomycin `9A)` has the structure as shown below.
`Hoverset(13)(C)-=overset(12)(C)-overset(11)(C)-=overset (10)(C)H-overset(9)(C)H=overset(8)(C)=overset(7)(C)H(overset(6)overset(4)(C)H=overset(5)overset(3)(C)H)_(2)-overset(2)(C)H_(2)overset(1)(C)OOH(A)`
Which statement is correct ?
Stereochemistry at `C-10` and `C-12`, when compound `(A)` is hydrogenated with Lindlar's catalyst and Birch Reduction , rescpectively, is

A

`10E` and `12E` in both cases

B

(10Z,12Z) and (10E,12E), respectively

C

`(10E,12E)` and `(10Z, 12 Z )`, respectively

D

`10Z` and `12Z` in both cases

Text Solution

Verified by Experts

The correct Answer is:
b.
Hydrogenation with Lindar's catalyst and Birch reduction are syn and anti, respectively and both convert `(C-=C)` to `(C=C)`.
