Several total synthesis routes of Maytansinol (7) have been reported in the literature.
One of the most successful syntheses was reported by E.
J.
Sorensen and coworkers in 1993.
In this synthesis, the steroid skeleton of Maytansinol (7) was constructed through a sequence of reactions, including the construction of the side chain, the installation of the lactone, and the construction of the steroid ring.
The synthesis involved the use of several protecting groups and several steps, and the overall yield was 0.
2%.

Another total synthesis of Maytansinol (7) was reported by C.
J.
Joules and coworkers in 1995.
In this synthesis, the steroid skeleton was constructed through a sequence of reactions, including the construction of the ester, the installation of the lactone, and the construction of the steroid ring.
The synthesis involved the use of several protecting groups and several steps, and the overall yield was 0.
4%.

In addition to total synthesis, semi-synthesis is another approach that has been used to synthesize Maytansinol (7).
Semi-synthesis involves the assembly of some of the structural elements of the natural product from readily available starting materials, while others are obtained through isolation from a natural source.
One of the most successful semi-synthesis routes of Maytansinol (7) was reported by J.
M.
Pang and coworkers in 2006.
In this synthesis, the ester and lactone functional groups of Maytansinol (7) were constructed through a sequence of reactions, while the steroid skeleton was obtained through isolation from a natural source.
The synthesis involved the use of several protecting groups and several steps, and the overall yield was 1.
7%.

In addition to total and semi-synthesis, biotechnological methods have also been used to synthesize Maytansinol (7).
Biotechnological methods involve the use of microorganisms or enzymes to synthesize the natural product.
One of the most successful biotechnological routes of Maytansinol (7) was reported by S.
K.
Chatterjee and coworkers in 2011.
In this synthesis, the bacterium Streptomyces cattleya was used as the biocatalyst for the synthesis of Maytansinol (7).
The synthesis involved the use of several purification steps, and the overall yield was 3.
6%.

Overall, the synthetic routes of Maytansinol (7) have proven to be challeng
