Brief summary: This phase II trial studies how well vosaroxin and cytarabine work in treating patients with untreated acute myeloid leukemia. Drugs used in chemotherapy, such as vosaroxin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Detailed description: PRIMARY OBJECTIVES:

I. To assess the rate of complete remission (CR) after induction therapy with the combination of "7+V" (vosaroxin and standard dose infusional cytosine arabinoside \[ara-C\]) for patients with newly diagnosed, previously untreated acute myelogenous leukemia (AML).

SECONDARY OBJECTIVES:

I. Frequency of grade 3-5 adverse events related to administration of "7+V".

II. To evaluate for the presence of minimal residual disease (MRD) remaining after "7+V" induction and/or re-induction.

III. To determine the CR/CR with incomplete blood count recovery (CRi) rate after one and/or 2 cycles of "7+V" induction.

IV. To determine the time to neutrophil and platelet recovery following "7+V" induction.

V. To assess disease-free survival (DFS) at 1 year (yr) of patients achieving CR/CRi after "7+V" induction.

VI. To assess overall survival (OS) at 1 yr of all patients receiving protocol-defined therapy.

VII. To determine the correlation of hematopoietic stem cell transplant (HSCT) comorbidity index and Wheatley Index scores with disease response, DFS and OS.

TERTIARY OBJECTIVES:

* I. To describe the mutational burden of this cohort of AML patients.
* II. To correlate genomic aberration with response rate, DFS, and OS.
* III. To determine the number of patients treated with vosaroxin who eventually go to allogeneic HSCT.

OUTLINE:

Patients receive vosaroxin intravenously (IV) on days 1 and 4 and cytarabine IV continuously on days 1-7 (Induction-I). Patients with residual leukemia and for whom a second course is indicated in the judgment of the investigator may undergo a second course of treatment (Induction-II) 14-57 days after day 1 of Induction-1

After completion of study treatment, patients are followed every 3 months for 1 year.

Eligibility criteria: Inclusion Criteria:

* Ability to provide informed consent
* Ability to tolerate intensive therapy with vosaroxin 90 mg/m\^2 and cytarabine
* Eastern Cooperative Oncology Group (ECOG) performance status 0-2 at time of study entry
* Morphologically confirmed new diagnosis of AML in accordance with World Health Organization (WHO) diagnostic criteria
* Patients who have received hydroxyurea alone or have previously received "non-cytotoxic" therapies for myelodysplastic syndromes (MDS) or myeloproliferative neoplasms (MPN) (e.g., thalidomide or lenalidomide, 5-azacytidine or decitabine, histone deacetylase inhibitors, low-dose Cytoxan, tyrosine kinase or dual tyrosine kinase \[TK\]/SRC proto-oncogene, non-receptor tyrosine kinase \[src\] inhibitors) will be allowed
* Serum creatinine =\< 2.0 mg/dL
* Hepatic enzymes (alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\]) =\< 2.5 x upper limit of normal
